合成并聚合了甲基丙烯酸2-（4-（4 ′-甲氧基苯基）苯氧基]乙基酯、3-（4-（4 ′-甲氧基苯基）苯氧基]丙基酯、4-（4-（4 ′-甲氧基苯基）苯氧基]丁基酯、5-（4-（4 ′-甲氧基苯基）苯氧基]戊基酯和6-（4-（4 ′-甲氧基苯基）苯氧基]己基酯。在甲苯、三氯甲烷和四氢呋喃中，用tBuMgBr进行阴离子聚合，在甲苯中用偶氮二异丁腈（AIBN）进行自由基聚合。
2-(4-(4'-Methoxyphenyl)phenoxy]ethyl, 3-(4-(4'-methoxyphenyl)phenoxy]propyl, 4-(4-(4'-methoxyphenyl)phenoxy]butyl, 5-(4-(4'-methoxyphenyl)phenoxy]pentyl, and 6-(4-(4'-methoxyphenyl)-phenoxy]hexyl methacrylates were synthesized and polymerized. Anionic polymerization of these was carried out with tBuMgBr in toluene, CHCl 3 and THF at low temperature, and radical polymerization was conducted with AIBN in toluene.
