  • Patent number: 5180781
    Abstract: The process for the production of an alloy of cross-linked or partially cross-linked rubbers and aromatic polyesters basically consists of reacting a mixture of a rubber latex and an aqueous solution of an alkali metal or alkaline earth metal diphenolate with a solution of a dicarboxylic acid halide and/or a carbonyl halide in a water-immiscible solvent. An aromatic polyester forms at the water/organic solvent phase boundary and goes over into the organic phase. At the same time, the rubber migrates from the aqueous into the organic phase. When the organic phase is separated and the organic solvent removed, the alloy of rubber and oirganic polyester remaining behind is suitable for the production of moulded articles of all kinds.

  • Patent number: 5068285
    Abstract: Carbonate polymers (PC) such as randomly branched carbonate polymers, linear carbonate polymers and blends thereof are blended with ABS polymers and acrylonitrile-styrene-acrylate rubber (ASA) polymers as impact modifiers. The ABS polymers have greater than 18% acrylonitrile. The ASA impact modifier is in the PC and the ABS resin interphases so that higher melt elasticity is achieved.

  • Patent number: 5063112
    Abstract: Multi-layer plastic elements containing a polycarbonate core, with a polymethacrylate layer containing a UV absorber, and modified to be impact-resistant, applied to the core, where the polymethacrylate plastic layer is composed of methacrylate copolymers, which form compatible mixtures with polycarbonate, especially the polycarbonate of bisphenol A, exhibit good adhesion between the polycarbonate and the polymethacrylate. The methacrylate copolymers are methyl methacrylate copolymers with (meth)acrylic monomers which contain carbocyclic substituents in the ester group. The protective layer containing UV absorber is applied to the polycarbonate plastic in thickness from 1 to 500 .mu.m by coextrusion or by lacquering.

  • Patent number: 5049619
    Abstract: Two-component polymeric compositions having two interconnected solid phases, and exhibiting spinodal decomposition morphology at the domain boundaries are shown, as are methods for forming the same. The compositions are prepared from two different polymers one of which possesses ductility in that it shows substantial yield behavior under tensile stressing, the other being brittle, exhibiting no such behavior; thermoplastic polymers, in conjunction with thermotropic liquid crystalline materials, exemplify such systems. The desired morphology is created by preparing the two component compositions in a single solid phase below the lower critical solution temperature of the compositions, and thereafter heating the compositions above such temperature to form a two-phase system.

  • Patent number: 5041504
    Abstract: Copolymer-containing compositions are prepared by the reaction of an epoxytriazine-capped polyphenylene ether with another polymer containing amine end groups, especially a polyamide, under intimate blending conditions. The compositions have excellent properties and find utility as molding compositions and as compatibilizers for blends of similar polymers. Suitable epoxytriazine-capped polyphenylene ethers may be prepared by reaction of a polyphenylene ether with an epoxychlorotriazine such as diglycidyl chlorocyanurate, n-butyl glycidyl chlorocyanurate or mesityl glycidyl chlorocyanurate.
