Themicrophotographs showed that the emulsion of the acrylate-vinyl acetate copolymer posse-ssedcore-shell structure.When different feed ratio was used the monomer predominantin fee-ding comprised core,by using various means of feeding the monomer first added polymerized and formed core first.The microstructure showed obvious effect on the mechanical properties,T_g and water-resistance of the latex film cast from the emulsion.Based on the study on the microstructure of emulsion particle it is considered that when the content of vinyl acetate was more than 50mol% in feeding the initiation and nuclei formation of the copolymerization proceeded in water phase.
- Acrylate-vinyl acetate copolymer,
- Emulsion polymerization,
- Core-shell structure,
