Ym. Wu et al., Preparation and performance in paper coating of silicone-modified styrene-butyl acrylate copolymer latex, J APPL POLY, 79(2), 2001, pp. 333-336
Silicone-modified styrene-butyl acrylate copolymer latex was synthesized by
emulsion copolymerization by using octamethylcyclotetrasiloxane (D-4), sty
rene, and butyl acrylate as raw materials, potassium persulfate as initiato
r and propylmethacrylate triethoxysilane (KH-570) as crosslinking agent. Th
e infrared spectra studies showed that the vinyl monomers were completely c
opolymerized with D-4. The prepared silicone-modified copolymer latex with
the interpenetrating polymer networks tended to have higher stability, and
better toluene and water resistance than styrene-butyl acrylate latex. The
glossiness of coated paper was improved with silicone-modified copolymer la
tex, and it was at a maximum when D-4 was about 3% of total monomers. (C) 2
