| 摘 要： | 本文研究了受阻胺TMP、TMPM、TUV-770对MMA、St本体聚合的影响。无论用BPO或AlBN引发MMA聚合时,TMPM或TUV-770都能延长诱导期,但对R_p的影响较小,而TMP能使R_p略增。测定了聚合反应的表观活化能和动力学方程。

| Abstract: | The effects of hindered amines, such as 2,2,6,6-tetramethyl-4-hydroxy-piperidine (TMP)> 2,2,6,6-tetramethyl-4-piperidinyl methacrylate (TMPM), TUV-770, on methyl methacrylate (MMA) and styrene (St) homopolymerization have been studied. It was found that in the MMA polymerization initiated by benzoyl peroxide (BPO) or 2,2'-azo-bis-isobutylonitrile (AIBN), the presence of TMPM or TUV-770 delayed the induction period and a little change on Rp was observed. However, in the presence of TMP Rp increased slightly. The activation enrgy of polymerization was datermined, and the polymerization rate equation for BPO-TMPM system is obtained as follows: RP = XBPO]1/2 MMA] . |
