新型螺环交联剂的合成及其交联聚合反应

SYNTHESIS OF NEW SPIRO CROSSLINKING AGENT AND CROSSLINKING POLYMERIZATION OF MMA

合成了一种新型螺环环丙烯酸酯交联剂３，１１二亚甲基２，１０二酮１，４，９，１２四氧二螺［４，２，４，２］十四烷（２）．在过氧化苯甲酰（ＢＰＯ）引发下，在苯溶液中进行了它与甲基丙烯酸甲酯（ＭＭＡ）的自由基聚合反应．得到的交联聚合物是具有螺环交联结构的聚甲基丙基酸甲酯．交联聚合物分别在酸性和碱性条件下水解．结果表明，此交联离聚物在酸碱条件下都很稳定，特别是在酸性条件下。

A new type of spiro crosslinking agent,3,11 dimethylene 2,10 dione 1,4,9,12 tetraoxodispirobutadecane(2),was synthesized successfully.Its crosslinking polymerization with MMA was carried out at 80℃ in benezne with BPO as initiator.The resulting polymer is of spiro crosslinked structure.Hydrolyses of the crosslinked polymers were undertaken at acidic and basic condition.The results of the hydrolyses have shown that the crosslinked polymer has good resistance to acidic and basic hydrolyses.
