以苯乙烯(St)、丙烯酸异辛酯(2-EHA)为主要单体采用预乳化半连续种子乳液聚合工艺合成了苯丙乳液.用激光粒度仪测试了乳胶粒粒径大小及粒度分布,用差示扫描量热法(DSC)测试了共聚物的玻璃化转变温度,用流变仪测量了乳液的流变性能,研究了单体配比、交联剂用量以及乳化剂用量对乳胶粒粒径、乳液的稳定性、流变性、粘结性能的影响.结果表明:合成的苯丙乳液为假塑型流体；乳液的粘度随着2-EHA/St配比、交联剂用量和乳化剂用量的增加而升高;乳液的稳定性随着乳化剂用量的增大而提高,随着交联剂用量的增大而降低；乳液胶膜的粘结性随着交联剂用量以及2-EHA/St配比的增大而增强;乳胶粒的粒径随着乳化剂用量的增加而变小,随着交联剂用量的增加而变大.
