摘要
研究了乳化剂、交联剂与引发剂用量对（ＰＳ－ＰＭＭＡ）／（ＰＢＡ－ＰＡＡ）核壳结构ＬＩＰＮ乳液性能及膜性能的影响；探讨了乳化剂用量为３．０％时，乳液凝聚率、化学稳定性、转化率及粘度变化发生转折的原因；用Ｎｉｅｌｓｅｎ公式求得交联剂用量为０．４％时，交联点间链平均分子量Ｍ≈３．８×１０３。
The influence of the concentration of the initially emulsifier,the crosslinking agent and the initiator on the performance of both emulsion and films of LIPN(PS-PMMA)/(PBA-PAA) with core-shell structure was investigated. The reason why coagulating rate, chemical stability,conversion and adhesive of LIPN emulsion sharply changed at about 3% emulsifier concentration was discussed.The chain everage molecular weight between cross-linked point,is obtained at the 0.4% concentration of crosslinking agent according to the Nielsen formula.
