Ethylenic Reactant Contains A Carbonate Group Patents (Class 525/277)
  • Patent number: 4408016
    Abstract: Discloses a monomeric composition and the polymeric product thereof. The composition contains a major portion of diol bis(allyl carbonate) monomer, and effective amounts of a multifunctional acrylate monomer, and a viscosity increasing polymer. Also disclosed is a method of reducing the haze in polymeric compositions of (a) a diol bis(allyl carbonate) and (b) a viscosity increasing polymer, by the addition of a multifunctional arcylate monomer to the monomeric composition prior to the polymerization thereof.

  • Patent number: 4346197
    Abstract: Disclosed are polymer blends of bis(allyl carbonate) polymers with polymers of olefinically unsaturated monomers, and the precursor blends of bis(allyl carbonate) monomers with polymers of olefinically unsaturated monomers, and fabricable resins prepared therefrom. Also disclosed is a method of fabricating, e.g., molding, injection molding, extruding, and the like, the fabricable resins. The bis(allyl carbonate) polymer blend is taken to a fabricable state, i.e., a fusible pseudoplastic that does not lose liquid on fabrication, either by admixture or admixture and reaction. The fabricable resin is then fabricated, e.g., extruded, molded, or the like, and then polymerized to a hard polymer. Also disclosed are blends of bis(allyl carbonates), monomeric and polymeric, with polymers having olefinic unsaturation.

  • Patent number: 4289675
    Abstract: An air drying latex coating composition, curable under ambient conditions, is described having copolymer particles consisting essentially of copolymerized monoethylenically unsaturated monomers dispersed in an aqueous emulsion. The copolymer particles have 0.5-30% by weight of ethylenically unsaturated monomers bonded thereto through reacted C.sub.1 -C.sub.6 N-alkylol functionalities. Curing agents or curing catalysts are also present to cure the deposited composition. The coating compositions are provided by forming an aqueous dispersion of the copolymer particles, bonding an ethylenically unsaturated monomer thereto through a C.sub.1 -C.sub.6 N-alkylol functionality, and admixing therein a curing catalyst or curing agent.

  • Patent number: 4217433
    Abstract: When an acrylic monomer such as methyl methacrylate is copolymerized with an allyl monomer such as allyl methacrylate whereby the resulting copolymer has active pendant allyl groups, this copolymer is then crosslinked with diethylene glycol bis (allyl carbonate) monomer (called ADC). The resulting product has considerable reduction in shrinkage while maintaining optical clarity and is useful as lenses.

  • Patent number: 4205020
    Abstract: A graft copolymer comprises a substrate of a diene rubber, and a homogeneous superstrate containing units of acrylonitrile and at least one aromatic olefin having a molar ratio of acrylonitrile to olefin between 2 and 9. The superstrate may also contain a minor amount (preferably less than 10 mole %) of at least one other comonomer selected from acenaphthylene, vinyl carbazole and its derivatives, maleimide and its N-substituted derivatives and norbornene and its derivatives.
