  • Publication number: 20140275425
    Abstract: The present invention relates to an inner-plasticized vinyl chloride-based copolymer resin not requiring plasticizers and a preparation method thereof. Specifically, the vinyl chloride-based copolymer resin is prepared by a suspension polymerization method of initiating the polymerization of vinyl chloride monomer, feeding a certain amount of butyl acrylate continuously or discontinuously thereinto and carrying out the additional polymerization at the temperature higher than the polymerization initiation temperature so as to prepare a core-shell type vinyl chloride-based random copolymer resin. The vinyl chloride-based copolymer resin of core-shell structure prepared by the present invention includes vinyl chloride-butyl acrylate copolymer, and it can provide a vinyl chloride-butyl acrylate copolymer product which can be processed without plasticizers positively necessary to produce a soft product.

    Abstract: A process for the synthesis of a diene copolymer comprising at least two blocks, at least one of the blocks being composed of a diene elastomer, characterized in that it comprises a stage of 1,3-dipolar reaction of two polymers defined as being: a) a diene elastomer bearing an alkyne functional group at one or each of its chain ends, and b) a polymer bearing at least one azide functional group. This process of synthesis can be adjusted, whatever the nature of the monomers necessary to form each of the blocks of the copolymer. Each block can be synthesized with an appropriate chemistry, independently of the other block.

  • Publication number: 20140066566
    Abstract: The present invention relates to use of a novel, single-component additive for addition to thermoplastics, in particular polyvinyl chloride (PVC). The resultant reduced friction delays melting of the thermoplastic during extrusion and therefore improves fluidity and lowers the process pressure required. The reduced friction moreover facilitates processing in shaping machinery by reducing adhesion to metal. In order to provide these technical improvements, the present invention provides a novel poly(meth)acrylate-based additive for thermoplastics, in particular for PVC. This features a poly(meth)acrylate backbone and long alkyl solid chains.
