| Abstract: | St BA MAA composite polymer latexs were prepared using three different feed methods and two different feed sequences. The latexs particle size, distribution were characterized by PCS and the merphology were observed by TEM. The distribution of carboxic function group in latexs and alkic thicken nature were analyzed. Water and solvent resistance of the latex films were detected. The relationship among polymerization methods, mucleation and growth mechanism of the particle, particle microstructure, properties of latexs and films was discussed. |
