Unplasticized poly(vinyl chloride)(PVC) is brittle and notch-sensitive. In this thesis, organic rubber particles and organic/inorganic particles were applied to toughen PVC Acrylate polymer (ACR) latex particles with poly(butyl acrylate) core and poly(methyl methacrylate) or PVC shell, were synthesized by seeded emulsion copolymerization. ACR-g-VC and ACR-g-VC/nano-hydrotalcite resins, were prepared by vinyl chloride (VC) suspension copolymerization in the presence of ACR latex or ACR latex/nano-hydrotalcit...
