Abstract: Plasticized polyvinyl chloride particles are prepared by dispersing a plasticol in an agitated liquid medium immiscible therewith maintained at about 100*-140*F. The liquid medium is agitated so that the plastisol is dispersed as small droplets of essentially spherical form having a particle size not exceeding about 0.03 inch. The liquid medium is then heated to a temperature above about 150*F, e.g., up to about 350*F but advantageously to a temperature up to the boiling point of the liquid medium, to achieve gelation of the plastisol droplets, which are then separated from the liquid medium. The resulting plasticized particles are of essentially spherical form and have an advantageously narrow particle size distribution range. The particles are essentially dust free and have highly desirable free flowing characteristics. Blends of two or more plastisol compositions, e.g., of different color, can readily be obtained.

Abstract: The surface gloss and appearance of vinyl plastisol coatings adhered to substrates are improved by a process comprising passing the coated substrate in cooled condition in contact with a surfacing roll maintained at a temperature of about 320*-420*F and a contact pressure of about 2-100 pounds per linear inch.

Abstract: DECORATIVE SHEET MATERIALS SUCH AS FOAMED VINYL FLOOR COVERINGS COMPRISING, PREFERABLY, A BASE OR SUBSTRATE SUCH AS ASBESTOS, FELT, A LAYER OF FOAM OR CELLULAR RESIN MATERIAL ON THE BASE HAVING PORTIONS OF DIFFERENT THICKNESS PROVIDING A RELIEF PATTERN, THE FOAM OF THE LANDS HAVING RELATIVELY LARGE CELLS AND THE FOAM OF THE VALLEYS BEING CRUSHED AND HAVING SMALLER CELLS WHICH CELL WALLS BONDED TO EACH OTHER, A LAYER OF NONCELLULAR TRANSPARENT RESIN MATERIAL OVERLYING BOTH THE LAND AND VALLEY AREA OF THE RELIEF PATTERN, AND A PRINTED COLOR PATTERN FOR DESIGN BEING PROVIDED BETWEEN THE FOAM RESIN LAYER AND THE TRANSPAENT RESIN LAYER, WITH COLOURED AREAS OF THE PATTERN OR DESIGN IN ACCURATE REGISTRATION WITH AND/OR PREDETERMINED RELATION TO THE CRUSHED OR VALLEY AREAS OF THE FOAM LAYER. IN ADDITION TO THE RELIEF AND COLOR PATTERNS, THE PRODUCT MAY ALSO HAVE A THIRD PATTERN EFFECT IN REGISTRATION WITH THE RELIEF AND COLOR PATTERNS, I.E., A PATTERN OF DIFFERENT LIGHT REFLECTIVE CHARACTERISTICS AT THE EXPOSED SURFACE OF THE TRANSPARENT LAYER. APPARATUS AND METHOD FOR PRODUCING THE COVERING MATERIALS ACCORDING TO THE INVENTION ARE ALSO DISCLOSED.
