摘要： 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.

摘要： 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.
