A method for the production of a modified ethylene - vinylcyclohexane - copolymer resin

摘要

A method for the production of a modified ethylene - vinylcyclohexane - copolymer resin, comprising the steps of:(1) Mixing at least the following components (a) to (c) for the production of a mixture:(A) 100 parts by weight of an ethylene - vinylcyclohexane - copolymer resin,(B) 0,1 to 20 parts by weight of at least one compound selected from:(B1) a compound which, in its molecule (i) at least one carbon - carbon double - or triple bond and (ii) at least one polar group, and(B2) a compound which, in its molecule (iii) a or radical and (iv) at least two identical or different functional groups, which are selected from a carboxylic acid - group, an acid halide - group, an acid anhydride - group, an acid halide anhydride - group, an acid esters - group, an acid amide - group, an imide - group, a imido - group, an amino - group and a salt of an amino - group, in which r is a hydrogen atom, an alkyl radical, an aryl radical, an acyl radical or a carbonyl dioxy radical is,the component (b) of maleic anhydride, maleic acid, fumaric acid, itaconic anhydride, itaconic acid, glycidyl (meth) acrylate or 2 - hydroxyethyl methacrylate contains,and(C) 0,01 to 20 parts by weight of an organic peroxide, and(2) Melt kneading of the mixture in a kneading apparatus, in order to provide a modified ethylene - vinylcyclohexane - copolymer resin to produce.
