Abstract

A new type of cross-linked copolymer granule was synthesized via emulsion polymerization and was characterized by FTIR spectroscopy. The O-carboxymethyl-chitosan was used as emulsifier for the copolymerization of methyl methacrylate and diacetone acrylamide. The resulting copolymer latex showed good compatibility with natural rubber. Morphology and surface roughness of modified natural rubber were measured by SEM and AFM. The tensile strength of natural rubber film reaches the maximum when the amount of additive was about 4%. Glass transition temperature and aging resistance were elevated. Protein spillage dropped in ca. 5 times, which could meet the minimum of the allergy protein.

O-羧甲基壳聚糖对甲基丙烯酸甲酯和双丙酮丙烯酰胺聚合物改性天然橡胶的影响

摘要

通过乳液聚合合成了一种新型的交联共聚物颗粒，并通过FTIR光谱对其进行了表征。将O-羧甲基-壳聚糖用作乳化剂用于甲基丙烯酸甲酯和双丙酮丙烯酰胺的共聚。所得的共聚物胶乳显示出与天然橡胶的良好相容性。通过SEM和AFM测量改性天然橡胶的形貌和表面粗糙度。当添加剂的量为约4％时，天然橡胶膜的拉伸强度达到最大。玻璃化转变温度和耐老化性提高。蛋白质泄漏量下降约 5次，可以满足最小的过敏蛋白。
