由于聚丙烯酸酯乳液具有耐热、耐光和耐老化等优点在涂料工业中得到了广泛的应用，但普通的聚丙烯酸酯乳液还存在耐水性差、低温下不易成膜、高温发粘以及含乳化剂的废液会对环境造成污染等缺点，因此，本文结合无皂乳液聚合和核壳乳液聚合技术，合成了聚丙烯酸丁酯/丙烯酸钠齐聚物，并以此为乳化剂，采用种子半连续法合成了以聚丙烯酸丁酯为核，聚甲基丙烯酸甲酯-苯乙烯为壳的无皂核壳聚丙烯酸酯乳液。

Results showed that the hybrid monomer could photopolymerize effectively and both free radical and cationic polymerization processes were improved. When 2-Hydroxy-2-methyl-1-phenyl-1-propanone (1173) was introduced into hybrid system containing UVI-6976, the final conversion of propenyl ether double bond and polymerization rate increased obviously. The comparison of photopolymerization kinetics between hybrid and blend system was investigated as well.
