摘要：Graft acrylates and siloxane copolymer latexes were prepared by batch process via simultaneous radical and ring-opening copolymerization. Vinyl septamethyl cyclotetrasiloxane (VD4) was used as a coupling agent to form chemical bonds between polyacrylates and polysiloxane. The occurrence of graft copolymerization was confirmed by Soxhlet extraction and by the dynamic mechanical properties of later polymer. The results showed that polymerization behavior and final rater stability strongly depend on siloxane content, with increase in siloxane content monomer conversion and later stability decreased. The mechanical properties of Inter film were influence not only by total siloxane con tent, but also by relative amount of VD4 to siloxane. (C) 1997 by John Wiley & Sons, Ltd.
