  • ACRYLIC COPOLYMER FOR USE IN HIGHLY FILLED COMPOSITES
    Publication number: 20130122227
    Abstract: The invention relates to an acrylic copolymer additive useful as a process aid in highly filled polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) composites. The acrylic additive is especially useful in highly filled PVC flooring tiles, rolled flooring, pipe and siding. The acrylic copolymer additive contains from 50 to 79 weight percent of methyl methacrylate monomer units, and has a Tg of less than 90° C.
    Type: Application
    Filed: December 19, 2012
    Publication date: May 16, 2013
    Applicant: Arkema Inc.
    Inventors: Paul R. Lavallee, Mark L. Lavach, Rong M. Hu

  • Pvc/Wood Composite
    Publication number: 20080261019
    Abstract: The present invention relates to a thermoplastic/natural cellulosic fiber composite, and more specifically to a high molecular weight compatibilizer within that composite resulting in both a high flex strength and high modulus and significant reduction in water absorption. The compatibilizer is preferably a terpolymer comprising: a) 0.5-20 percent by weight of monomer units selected from the group consisting of maleic anhydride, substituted maleic anhydride, mono-ester of maleic anhydride, itaconic anhydride, maleic acid, fumaric acid, crotonic acid, acrylic acid and methacrylic acid; b) 0 to 40 percent by weight of monomer units selected from styrene and functionalized styrene; and c) 40 to 98.5 percent by weight of monomer units selected from the group consisting of C1-8 alkyl acrylates and methacrylates, and vinyl acetate.
