By grafting copolymerization of hydrogen containing polymethylsiloxane(PHMS) and acrylic ester monomer

a new kind of hydrogen containing polymethylsiloxane(PHMS)/butyl acrylate(BA)/hydroxymethyl amide(NMA) composite emulsion was prepared which possessed excellent properties of the components. The paper discussed the effect of PHMS

NMA and initiator amount on the conversion

the stability of polymerization

storage and viscosity of this composite emulsion. The particle size of latexes prepared by different reaction condition was measured by transmission electron microscope(TEM) and particle size measuree.The polymerization mechanism

the polymer molecule structure and the film forming properties of the latexes were also investigated.The results showed that the PHMS/BA/NMA copolymer was obtained by emulsion polymerization and the copolymerization between PHMS and BA

NMA and homopolymerization of BA were simultaneously existing in the systems.Stable PHMS/BA/NMA composite emulsion with moderate particle size

Viscosity and high conversion could be produced when the proportion of raw materials such as PHMS.NMA and initiator was suitable.The film made from this composite emulsion had good film forming properties and other excellent properties.
