Heterocyclic Reactant Contains 1,2-epoxy Group Patents (Class 525/208)
  • Patent number: 9193878
    Abstract: The present disclosure relates to an improved electrocoating coating composition wherein the improvement is the addition of a non-water reducible anticrater agent. The non-water reducible anticrater agent is a polyesterurethane that is the reaction product of an aliphatic carboxylic acid anhydride, a monofunctional epoxy compound, a monofunctional alcohol and a diisocyanate and/or a polyisocyanate. The improved electrocoating composition provides cured coatings that have fewer craters and have a smooth surface when compared to coatings utilizing other anticrater additives.

  • Publication number: 20130209770
    Abstract: A film that is formed from a thermoplastic composition is provided. The thermoplastic composition contains a rigid renewable polyester and a polymeric toughening additive. The toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. An increase in deformation force and elongational strain causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This can result in the formation of a plurality of voids adjacent to the discrete domains that can help to dissipate energy under load and increase tensile elongation. To even further increase the ability of the film to dissipate energy in this manner, the present inventors have discovered that an interphase modifier may be employed that reduces the degree of friction between the toughening additive and renewable polyester and thus reduces the stiffness (tensile modulus) of the film.

    Abstract: Provided herein is a blend composition useful as a cross-linkable encapsulant layer and consisting essentially of two ethylene copolymers and optionally one or more additives. The first ethylene copolymer comprises copolymerized units of ethylene, optionally a first olefin having the formula CH2?C(R1)CO2R2, and a second olefin having the formula CH2?C(R3)COOH. At least a portion of the carboxylic acid groups have been neutralized to form carboxylate salts. The second ethylene copolymer consists essentially of copolymerized units of ethylene, optionally a first olefin having the formula CH2?C(R1)CO2R2, and a third olefin having the formula CH2?C(R4)D. R1, R3 and R4 represent hydrogen or an alkyl group; R2 represents an alkyl group; and D represents a moiety containing an epoxy group. Further provided are solar cell modules comprising the encapsulant layer.
