| abstract |
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. |
