  • Coating of vinylidene fluoride polymer and fluorine containing graft copolymer
    Patent number: 5034460
    Abstract: A vinylidene fluoride-based polymer-containing coating composition provides coatings having weather resistance, chemical stability, surface lubricity, and enhanced adhesion to substrates. The composition comprises:(a) a vinylidene fluoride-based polymer;(b) a graft polymer formed from the graft polymerization of an alkyl methacrylate onto a fluorine-containing polymer; and(c) at least one organic solvent.
    Type: Grant

  • Laminate of polyvinylidene fluoride bonded to thermoplastic resin
    Patent number: 4563393
    Abstract: A laminate consisting essentially of a layer of a thermoplastic resin (A) and a layer of a vinylidene fluoride resin (B), the layer of the resin (A) containing (C) polymerized units of an ethylenic unsaturated carboxylic acid ester in a proportion of 3 to 80% by weight based on the total weight of the layer of the resin (A). The polymerized units (C) of an ethylenic unsaturated carboxylic acid ester may exist either as a copolymer constituent of the resin (A) or in the form of an ethylenic unsaturated carboxylic acid ester polymer (C') blended in the layer of the resin (A).

  • Process for producing polymer having functional groups at its chain terminals
    Patent number: 4083834
    Abstract: A process for producing a polymer having functional groups at its chain terminals, which comprises reacting a polymer having alkali metal atoms at its chain terminals with an alkylene oxide or sulfide in a hydrocarbon medium having a solubility parameter of 7.2 or less at 25.degree. C. This process makes it possible to produce the said polymer in a short period of time without necessitating a large power for agitation. According to this process, there can be produced a polymer having a functionality near the theoretical functionality in a short period of time.
