摘　　要：采用半连续种子乳液聚合工艺制备核壳结构的聚丙烯酸丁酯/(聚甲基丙烯酸甲酯—衣康酸—双酚A环氧树脂)(PBA/P(MMA-ITA-DGEBA))乳胶粒子。并通过红外光谱仪(IR)对乳胶粒子进行了表征,证明乳胶粒子具有核壳粒子结构。将壳层带有环氧基的核壳乳胶粒子对环氧树脂进行增韧,通过扫描电子显微镜(SEM)对固化物冲击断面进行观测,改性核壳乳胶粒子对环氧树脂起到明显增韧效果,并提升了与环氧树脂的相容性。The PBA/P （MMA-ITA-DGEBA） latex particles were prepared by semi-continuous seed emulsion polymerization process. FI-IR was used to characterize latex with core-shell structure. Epoxy resin was toughened by latex particles with an epoxy-based core-shell. Cross section of cured resin was observed by SEM micrograph. A significant effect was significant effect in toughening of modified core-shell latex particles. Compatibility between modified core-shell latex and epoxy resin were improved.
