✦ Synopsis

In this paper, the latex interpenetrating polymer network poly(n-butyl acrylate) polystyrenelpoly(methy1 methacrylate) (PBAIPSIPMMA, or PBSM) was synthesized by microagglomeration and three-stage emulsion polymerization. The initial poly(n-butyl ac ylate) latex particle was agglomerated by methac ylic acid residue containing the polymer latex and then encapsulated by PS and PMMA.

The polyblend of polyhinyl chloride) (PVC) and PBSM (PVCIPBSM) was prepared by blending PVC and PBSM.

The morphology and properties of the polyblend have been studied. Experimental results have shown that the processability and impact-resistance of PVC can be enhanced considerably by means of blending 6-20 per hundred resin (phr) PBSM. The three-layered latex interpenetrating polymer network is a promising modifier for rigid PVC (RPVC) manufactures.
