Impact Modification of PVC with PBA/PMMA Core/Shell Composite Particles
Abstract:
Polyvinyl chloride(PVC) were toughened with polybutyl acrylate/polymethyl methacrylate core/shell impact modifier. The relationship between impact modifier's structure and its toughening efficiency to PVC was studied. Experimental results indicate that the toughening efficiency increases with particle size of the modifier. The optimum structure for the modifier is core/shell ratio 72/28~82/18, particle size 0.22 μm, fraction of crosslinking and grafting agent 0.5%~1.0%, respectively. SEM and TEM study on the morphology of the modified PVC shows that the impact modifier is uniformly dispersed in the PVC matrix.
