| 摘 要： | <正> 苯乙烯(简称St)-4(甲基丙烯酸)2,2,6,6-四甲基哌啶醇酯(简称MTMP)共聚物(简称PDS)是七十年代发展起来的一种新型高效光稳剂。本文用IR研究了一系列自由基聚合的PDS共聚物,找出了MTMP对序列结构敏感的吸收峰,发现MTMP的1152.5厘米~(-1)峰位置与三单元序列分布F_(SMS)值有一定线性关系,还对通过测量MTMP羰基伸缩振动ν_(C=O)峰位置来计算二单元序列分布P_(mm)的关系进行了讨论。 |

| Abstract: | A series of styrene (st) and 2, 2, 6, 6-tetramethyl-4-piperidinyl methacrylate (MTMP) copolymers were prepared by free radical copolymerization and their IR spectra were measured.It was discovered that the 1152.5 cm-1 band of MTMP was shifted to lower wave numbers with a decrease in the content of MTMP in the copolymer.This displacement of wave number of this band is approximately proportional to Fams which is called triad sequence distribution.The diad sequence distribution Pmm which was calculated through measuring the position of the ve=O of MTMP was discussed. |
