Preparation of novel reactive plastisol based on poly(vinyl chloride) and multifunctional acryl esters

摘要

Poly(vinyl chloride) (PVC) powder was mixed with various polyfunctionalacryl monomers as plasticizers to prepare acrylate-modified plastisols. This class of plastisol was hardened into the B stage without reaction and then cured into a harder material through crosslinking of the acrylate. The best formulation was attained after evaluation of various acrylates, PVC grades, and peroxides. Several difunctional acrylates with solubility parameters similar to that of PVC could be most conveniently used as the plasticizer. A sheet molding compound was obtained by the combination of the resultant plastisols with glass fiber by compression molding using conventional machines. It was cured into a PVC-based fiber reinforced plastic with high performance. This class of acrylate-modified plastisol is called reactive plastisol. (C) 2000 John Wiley Ss Sons, Inc. [References: 6]
