Abstract:
An elasticized, dispersion-grade vinyl chloride resin powder is provided which not only imparts improved elasticity and reduced hysteresis losses to fluid plastisols made therewith, but also has excellent stability under adverse environmental conditions, insuring consistent performance in plastisols even after said powder has been in storage for several months. This resin powder has an average particle size between about 0. 4 and about 4 microns and contains between about 0. 5 and about 20% by weight of an elastomeric acrylic polymer having a T. sub. g below about -10. degree. C. which is present as discrete particles most of which are at least partly occluded by hard thermoplastic vinyl chloride polymer formed in situ, which vinyl chloride polymer represents substantially all of the remaining mass of said powder. Fluid plastisols prepared from said resin powder are also described as well as finished articles of improved resiliency and elasticity, which are made from said plastisols. Also disclosed, are preferred methods of preparing said elasticized resin powders.
