Disclosed are compositions comprising plasticizer, first organic polymeric material fused or fusible in the plasticizer and second polymeric material not fusible in the plasticizer, said second polymeric material having a softening point temperature less than about the fusion temperature of the first polymeric material in the plasticizer. The first polymeric material preferably comprises vinyl resin and the second polymeric material preferably comprises acrylate polymers in particulate form. Also disclosed are methods for producing surface coverings comprising converting the liquid plastisols of the present invention to solid compositions under time and temperature conditions sufficient to enable softening, and preferably substantial softening and swelling, of the second polymeric material prior to fusion of the liquid composition.
A decorative surface covering comprising a layer of a solid composition comprising plasticizer, first organic polymeric material fused in said plasticizer and particles of second polymeric material comprising particles of poly(ethylene methacrylate) in an amount of from about 10 percent to about 25 percent by weight of said solid composition not fused in said plasticizer, said plasticizer increasing the flexibility of said first polymeric material, said particles of second polymeric material having a softening point temperature below about the fusion temperature range of said first organic polymeric material in said plasticizer, whereby said particles are substantially swollen and deformed particles.
A decorative surface covering comprising a layer of a solid composition comprising plasticizer, first organic polymeric material fused in said plasticizer and particles of second polymeric material not fused in said plasticizer, said plasticizer increasing the flexibility of said first polymeric material, said particles of second polymeric material comprising particles of acrylate polymer and having a softening point temperature below about the fusion temperature range of said first organic polymeric material in said plasticizer, wherein said first organic polymeric material comprises polyvinyl chloride particles having a mean particle size of from 0.02 micron to about 25 microns and whereby said particles of second polymeric material are substantially swollen and deformed particles.
A process for producing a surface covering composition comprising:
