1) Two spiromonomers (CMA : 2-oxo-5-metbacryloxymechy1-1, 3-dioxane, VBECC : 2-oxo-5-etbyl-5-(p-vinylbenzyloxy)methy1-1, 3-dioxane) were synthesized and identified by JR and NMR spectra, and elemental analysis.2) Three kinds of comonomers of CMA with MMA that differs were polymerized in the benzene solution with AIBN as initiator. The chemical ratio and characterization of the cornonomers which is obtained were as follows CMAIMMA=35/65(Mn=47000, Mw/Mn=3.14), 44/56(Mn=40400, Mw/Mn=1.99) and 55/45(Mn= 47000, Mw/Mn=1.88)Three kinds of polymethylmethacrylates that have S-rnechionine oxidant in the side chain were synthesized and examined its solubility into MMA solution. As results a polymethylmethacrylate derivative with Soxidant have an excellent solubility into MMA and does not inhibited the polymerization of MMA.4) A spirocarbonate methacrylate, CMA with excellent solubility into the methacrylate monomers(ethyleneglycol dimethacrylate(1G), triethyleneglycol dimethacrylate(3G) and n-butylmethacrylate), in addition, it was confirmed that the heat-polymerization of those monomers is accelerated. Also the polymerization of vinyl group and ring-opening polymerization of spirocyclic group in CMA were verified and its polymers were insoluble into acetone solution.

1)两种螺环单体（CMA：合成了2-氧代-5-甲基苄氧基甲基-1，3-二氧六环（VBECC：2-氧代-5-乙撑基-5-（对乙烯基苄氧基）甲基-1，3-二氧六环），并通过IR、NMR和元素分析进行了结构鉴定。所获得的共聚单体的化学比和表征如下：CMAIMMA=35/65（Mn=47000，Mw/Mn=3.14），44/56（Mn=40400，Mw/Mn=1.99）和55/45（Mn= 47000，Mw/Mn=1.88）三种具有S-合成了侧链上的三甲基环氧化剂，并考察了其在MMA溶液中的溶解性。结果表明，聚甲基丙烯酸甲酯衍生物与氧化剂在MMA中具有优异的溶解性，并且不抑制MMA的聚合。4）螺碳酸酯甲基丙烯酸酯CMA在甲基丙烯酸酯单体（乙二醇二甲基丙烯酸酯（1G）、三乙二醇二甲基丙烯酸酯（3G）和甲基丙烯酸正丁酯）中具有优异的溶解性，此外，证实了这些单体的热聚合被加速。同时证实了CMA的乙烯基聚合和螺环开环聚合，其聚合物不溶于丙酮溶液。
