摘要

以２，４－二异氰酸甲苯，丙烯酸β－羟丙酯、正戊醇，正壬醇为原料，合成了２种不饱和丙烯酸化异氰酸酯单体（ＡＡＴ，ＮＡＴ），并用自动记录膨胀计测定了２种单体在２－羟基－２－甲基－１－苯基－丙－１－酮（Ｄａｒｏｃｕｒ１１７３），α，α－二甲氧基苯乙酮（ＤＥＡＰ），α，α－二甲氧基－α－苯基苯乙酮（ＤＭＰＡ）为光引发剂时的聚合速率。结果表明，单体的活性ＮＡＴ＞ＡＡＴ，引发剂的引发活性为ＤＥＡＰ≥ＤＭＰＡ＞Ｄａｒｏｃｕｒ１１７３，单体的聚合速率受溶剂影响。

Abstract

In this paper

two unsaturated acrylated isocynates(AAT

NAT) were synthesizedfrom 2.4-TDI

equimolarβ-Hydroxy propyl acrylate and aliphatic alcohol by addition reaction.The photopolymerization of monomers under UV light radiation at 40℃ with the use of Darocur1173

DEAP

DMPA as the photoinitiator have been studied by dilatometry. The study hasshown that the activity of monomer NAT is higher than that of AAT.the efficiency of photoini-tiator decreased in the order of DEAP>DMPA>Darocur 1173 for both monomers

and the poly-merization rate was greatly influenced by solvent.
