Novel vulcanizable mixtures comprising silicone-core, acrylate-shell rubber particles dispersed within a fluorocarbon rubber.

Mixture of fluorocarbon rubber and silicone/acrylate core/shell rubber

Thermoplastic fluoroelastomer graft polymers formed from a fluorine-containing graft polymer formed from a rubber like (Tg&lt;0.degree. C.), uncrosslinked fluorine-containing copolymer containing double bonds as the graft base onto which is grafted a fluorine-containing monomer that gives an at least partly crystalline polymer are produced from the rubber-like uncrosslinked copolymer by radical polymerization in solution, suspension or emulsion under elevated pressure at about -15.degree. to +120.degree. C., and grafting thereon a monomer which forms an at least partly crystalline polymer the grafting onto the rubber-like copolymer taking place by radical solution, suspension or emulsion graft polymerization under elevated pressure at about -15.degree. to +120.degree. C.

Thermoplastic fluoroelastomers produced by graft copolymerization

The invention relates to compatible blends of 94 to 10% by weight aromatic poly(ester) carbonates or polycarbonates, 5 to 70% by weight polyamides and 1 to 20% by weight ester-functional (meth)acrylate polymers and, optionally, elastomers in typical modifying quantities, to a process for the production of these blends and to their use for the production of moldings.

Compatible blends of aromatic poly(ester) carbonates and polyamides

Interpolymers of aromatic polyesters and cross-linked (or partially cross-linked) rubbers and a process for their production in which a mixture of a cross-linked rubber in latex form containing reactive groups and an aqueous solution of an alkali metal or alkaline earth metal diphenolate is reacted with a solution of a dicarboxylic acid halide and/or a carbonyl halide in a water-immiscible solvent so that an aromatic polyester forms at the water/organic solvent phase boundary, which polyester goes over into the organic phase and the rubber at the same time also goes into the organic phase. The interpolymer of rubber and organic polyester thus formed is suitable for the production of moulded articles of all kinds by the methods of thermoplastic shaping such as extrusion and injection moulding.

Interpolymers of aromatic polyesters and rubbers

The invention relates to poly(meth)acrylates having grafted-on polycarbonate chains, to their production and to their use as modifiers for thermoplastic polycarbonates having improved resistance to gasoline and/or improved impact strength at low temperatures and to their production.

The new polyester carbonate-polysiloxane block copolymers having recurrent structural units of the following formulae ##STR1## have improved resistance to petrol compared with known polyester carbonate-polysiloxane block copolymers. They are used for the manufacture of moulded products, in particular those used under the engine bonnet of a motor vehicle or as external parts of motor vehicles.

Thermoplastic polyester carbonate-polysiloxane block copolymers

Thermoplastic polydiorganosiloxane/polycarbonate block copolymers based on dihydroxydiphenylcycloalkanes corresponding to the following general formula (I): ##STR1## wherein R.sup.1 and R.sup.2 independently represent hydrogen, halogen, preferably chlorine or bromine, C.sub.1 -C.sub.8 alkyl, C.sub.5 or C.sub.6 cycloalkyl, C.sub.5 -C.sub.10 aryl or C.sub.7 -C.sub.12 aralkyl, preferably phenyl-C.sub.1 -C.sub.4 -alkyl, in particular benzyl: m represents an integer of from 4 to 7, preferably 4 or 5;

The new bisesters of unsaturated carboxylic acids corresponding to the following formula ##STR1## may be used in curable polyester resin mixtures which may in turn be used for the production of moldings. The curable mixtures obtainable from the new bisesters of unsaturated carboxylic acids show a higher glass transition temperature than normal polyester resins and, despite a higher crosslink density, show broader-mesh crosslinking.

Bisesters of unsaturated carboxylic acids, their production and their

The invention relates to the use of mixtures consisting of 5 to 95% by weight of an aromatic polycarbonate of which the linear chains contain from 0.1 mol-% to 50 mol-% bifunctional structural units corresponding to formula (1) ##STR1## and 95 to 5% by weight of a thermoplastic styrene polymer and, optionally, standard additives as substrates for optical storage media.

Thermoplastic moulding compositions of polycarbonate and terpolymers

Block copolyesters based on polyalkylene terephthalates which contain polydiene blocks show an extremely low deformation even when they are processed into thin articles. They still have a crystallinity which is decreased by less than the ratio corresponding to the polydiene portion.

The present invention relates to thermoplastic moulding compositions consisting of polycarbonates, graft polymers and copolymers, which are characterized in that they contain special graft polymers and/or special copolymers, with the result that these moulding compositions possess a very homogeneous rubber distribution and furthermore possess very good toughness and heat stability and substantially improved heat distortion resistance.
