KINETICS OF SUSPENDED EMULSION POLYMERIZATION OF METHYL METHACRYLATE

The kinetics of suspended emulsion polymerization of methyl methacrylate (MMA), in which water acted as the dispersed phase and the mixture of MMA and cyclohexane as the continuous phase, was investigated. It showed that the initial polymerization rate (Rp0) and steady-state polymerization rate (Rp) were proportional to the mass ratio between water and oil phase, and increased as the polymerization temperature, the potassium persulphate concentration ([I]) and the Tween20 emulsifier concentration ([S]) increased. The relationships between the polymerization rate and [I] and [S] were obtained as follows: Rp0 ∝ [I]0.73[S]0.32 and Rp ∝ [I]0.71[S]0.23. The above exponents were close to those obtained from normal MMA emulsion polymerization. It also showed that the average molecular weight of the resulting poly(methyl methacrylate) decreased as the polymerization temperature, [I] and [S] increased. Thus, MMA suspended emulsion polymerization could be considered as a combination of many miniature emulsion polymerizations proceeding in water drops and obeyed the classical kinetics of MMA emulsion polymerization.     

THEORETICAL ANALYSIS OF SPECTRUM OF TbP_5O_(14) WITH LIGAND FIELD THEORY

In this article, the extension of the irreducible tensor method to the ligand field theory, which has been performed by Tang Aoqing and his collaborators, is simplified by introducing the quasi-spin group to give a theoretical analysis of the spectra of TbP_5O_(14). The theoretical analysis is good coincidence with experimental results.     

CALCULATION OF EPR PARAMETERS OF THE LOW-SPIN.d~5 COMPLEXES

<正> Calculation result indicates that the lowest Kramer's doublet of the low-spin d5 complexes proposed by Prof. W. C. Lin and the first order approximate matrix derived by us from the 1.s matrix table of d1 ion and the hole energy level model put forward by Prof. W. C. Lin and Taylor respectively are more suitable to the calculation of EPR parameters of the low-spin d5 complexes. The calculation conditio gzz>gyy>gxx>0 established by Taylor is used by us to obtain two parameters simultaneously, i.e, the orbital reduction factor k of a positive number near to unity, and the rhombi-city λ in range from 0 to 1/3 which is a satisfactory quantitative para meter. The same accurate EPR parameters can be obtained from both this method and Griffith's method.

DIFFERENTIATION OF SOME YEAST SPECIES BY CAPILLARY GAS CHROMATOGRAPHIC ANALYSIS OF CELLULAR FATTY ACIDS

The cellular fatty acids from a total of 62 strains of Torulopsis glabrata (T. glabrata), Saccharomyces cerevisiae (S. cerevisiae), Rhodotorula rubra (R. rubra), Candida krusei (C. krusei), Candida albicans (C. albicans) and Candida tropicalis (C. tropicalis) were examined by capillary gas chromatography. On the basis of fatty acid composition, all strains could be differentiated as to species. These results indicate that capillary gas chromatographic analysis of cellular fatty acids is likely to be useful for rapid identification or grouping of newer isolates of yeast species.     

ISOLATION AND IDENTIFICATION OF β-N-OXALO-L-α,β-DIAMINOPROPIONIC ACID AND ITS ISOMER α-N-OXALO-L-α,β-DIAMINOPROPIONIC ACID FROM PANAX SPECIES

Meyer(cultivated ih Northeastern China), Panax quinquefolius L., Panax notoginseng F.H. Chen (cultivated in Southwestern China), Korean red ginseng and Jilin red ginseng were isolated and identified. Efficient separation and purification methods for β-N-ODAP and α-N-ODAP were developed.     

THE NUCLEOTIDE SEQUENCE OF SURFACE ANTIGEN GENE OF HEPATITIS B VIRUS SUBTYPE adr

The nucleotide sequence of the XhoI-BamHI fragment (1279bp), which contains the sur-face antigen gene (S gene) of HBVadr, was determined by Maxam and Gilbert's method.By comparing the differences both of the nuclectide sequence in the S gene and its codedamino acid sequence between adr and those reported for adw, ayw and adyw, some new var-iation sites were discovered. The differences were mainly distributed in the two hydrophilieregions. However, at those sites which might show biological function, there were no varia-tions among different subtypes, they are relatively conservative in heredity and evolution.Comparing the variation of the nucleotide sequence in the S gene region with that in thenon-S gene region, it is shown that the frequency of variation in the non-S gene regiondoubled that in the S gene region. Tim S gene region is more conservative.

RADIAL DISTRIBUTION FUNCTION (RDF) STUDY OF THE NONCRYSTALLINE STRUCTURE OF POLY P-PHENYLENE SULFIDE (PPS)

Owing to the existence of sulfur, a heavy atom, in the structure unit of PPS (C_6H_4S), P(r), the experimental reduced radial distribution function of its atomic-electronic density shows a group of finger print peaks in the range of 4—7 distinctly. According to the erystal structure model of PPS, an approximate P(r) curve is set up. Comparing it with the experimental results, we have discovered that the height of the 5th, 6th and 7th peak, which decreases with the decrease of sample erystallinity, is consistent with the damage of three interchain S—S distances (5.16 , 5.61, 6.76 ) in the erystal structure. And, correspondingly, the number of S—C distance is increased, which is consistent with the increase of the 4th and 7th peak height in the sample of noncrystalline state. The present authors hold that this is caused by the molecular chain displacement occurring along the direction of fibrous axis. The position of the 6th peak moving from 5.7 to 6.0 is referred obviously to the lateral space expansi     

A POSSIBLE MECHANISM OF FORMATION OF POLYNUCLEAR MOLYBDENUM CLUSTERS

The reported bi-eapped trinuclear molybdenum cluster anion(Mo_3S_2Cl_9)~(3-) is proposed to be formed first by adding a MoCl_2~(2 ) entity to a dinuclear molybdenum anion (Mo_2Cl_9)~(3-), followed by substitution of two S atoms for the triply bridging Cl atoms. The possible formation of (Mo_3Cl_(11))~- as an intermediate is supported by molecular orbital calculations. It may be possible to construct Mo_4Cl_(13)~ and Mo_5Cl_(15)~~(3 ) by a similar process.
