摘要

含有β二酮结构的烯类单体

如丙烯酰丙酮

分子中的β二酮部分存在着酮式烯醇式的互变异构现象［１～３］

张亦帆等对此进行了详细的研究［４］．ＣＨ２ＣＨＣＯＣＨ２ＣＯＣＨ３ＣＨ２ＣＨＣＯＨＯＣＨＣＣＨ３ＣＨ２ＣＨＣＯＨＯＣＨＣＣＨ３此类单体不同于一般的不饱和酮类的聚合

其聚合性质甚受互变异构的影响．对于甲基丙烯酰丙酮（ＭＡＡ）

丙烯酰丙酮（ＡＡ）和丙烯酰乙酸乙酯（ＡＥＡＡ）

Ｍａｓｕｄａ等详?...

Abstract

An acrylic monomer having βdiketonic moiety

i.e.3-acetyl-5-methyl-5-hexene-2

4-diketone(AMAA) was synthesized by reaction of acetylacetone and methacrylyl chloride in the presence of magnesium ethoxide.It has been found that AMAA is difficult to polymerize by free-radical initiation or heating due to the enol formating of βdiketonic moiety in the monomer.After the protection of the enol form in AMAA by treatment with trimethylsilyl chloride

the free-radical polymerization of AMAA can take place smoothly.The trimethylsilyl group can be removed easily by alcoholysis.It has been revealed by ESR analysis that the carbon atom which connected three strongly electron negative carbonyl groups in AMAA molecule forming a stable carbon free radical lead to retard the propagation during the free-radical polymerization.
