新型双官能团有机小分子催化剂的设计合成

In the paper, using a new combined initiating system, bifunctional redox system and other initiations, to polymerize acryl amide with homopolymerization post hydrolysis process and low initiating temperature, high molecular weight polyacrylamide was synthesized.

　以双官能度氧化还原引发体系为主,配合其它引发剂组成新型复合引发体系,在低温条件下采用均相水溶液聚合法引发丙烯酰胺均聚。

After validating the credibility of Differential Scanning Calorimeter (DSC) method by studying the decomposition of benzoyl peroxide (BPO), the decomposition kinetics of bifunctional peroxide initiator 2, 5-dimethyl-2 ,5-di(2-ethylhexanoylperoxy)hexane (DMDEHPH) and its polymerization products (PS-DMDEHPH)were investigated in detail at different heating rates.

在不同的升温速率下测定了双官能度过氧化物引发剂2,5-二甲基-2,5-二己酰基过氧化己烷(DMDEHPH)及其引发苯乙烯聚合生成的大分子引发剂(PS-DMDEHPH)的分解动力学,发现升温速率对分解动力学常数影响不大,得到其分解反应级数均符合一级反应规律,活化能分别为129。
