The Study of Synthesis of Hydrophobic Association Polyacrylamide Derivatives in Different Initiator Systems

摘 要 疏水缔合聚丙烯酰胺衍生物是一种大分子主链或侧链上含有少量疏水基团的新型水溶性功能高分子材料，在水溶液中具有良好的耐盐、耐温、增粘作用和贮存稳定性。利用分散聚合法，研究了采用不同体系的自由基引发剂及引发剂摩尔组成对聚合反应时间和聚合物分子量的影响，最终选择一种较好的引发体系。

Abstract The hydrophobic association polyacrylamide derivatives are new type water?soluble polymers that they have some hydrophobic groups in the main chains or side chains. They have good properties of temperature resistance,salt tolerance,tackability and storage in water solution. In the ex-periment, we use different systems of radical initiator and defferent mole ratio to study the effect of polymerization time and polymer molecular weight with dispersion polymerization. By the study, we can choose a good initiator system.
