制备了α-乙酰氧基丙烯酸甲酯和乙酯。在游离基引发剂的作用下,这两种单体,很容易进行聚合反应。它们的本体聚合物,都是无色透明坚韧的玻璃状固体。初步测得聚α-乙酰氧基丙烯酸甲酯的软化点为167°,α-乙酰氧基丙烯酸乙酯的软化点为148°,而用同样方法制得的聚甲基丙烯酸甲酯的软化点为126°,也就是说聚α-乙酰氧基丙烯酸甲酯和乙酯的软化点比聚甲基丙烯酸甲酯分别高出了约40°和20°左右。
Methyl alpha-acetoxyacrylate and ethyl ester were prepared. In the role of free radical initiator, these two monomers, it is easy to carry out the polymerization reaction. Their bulk polymers are colorless, transparent and tough glassy solids. The preliminary measurement of the poly-α-acetoxymethyl acrylate has a softening point of 167 ° and an α-acetoxyethyl acrylate of 148 °, whereas the softening point of the polymethyl methacrylate obtained by the same method Is 126 °, that is to say, the softening point of polymethyl α-acetoxyacrylate and ethyl ester is about 40 ° and about 20 ° higher than that of polymethylmethacrylate.
