WEATHER-RESISTANT RESIN OF HIGH SHOCK RESISTANCE, PROCESSABILITY, AND GOOD APPEARANCE

Title:

WEATHER-RESISTANT RESIN OF HIGH SHOCK RESISTANCE, PROCESSABILITY, AND GOOD APPEARANCE

Document Type and Number:

Japanese Patent JPS6112711

Kind Code:

A

Abstract:

PURPOSE: The titled resin that is obtained by grafting an aromatic vinyl, vinyl cyanide or the like onto an ethylene-α-olefin rubber, thus having a specific amount of soluble fraction and insoluble fraction to a specific solvent and showing good balance between shock resistance and processability.

CONSTITUTION: The graft polymerization of at least one selected from aromatic vinyl monomers such as styrene, vinyl cyanide monomer such as acrylonitrile and unsaturated carboxylic alkyl esters such as methyl methacrylate onto an ethylene-α-olefin rubber such as ethylene-propylene copolymer, preferably in an amount of 10W60wt% is carried out by the suspension or solution polymerization to obtain the objective resin of less than 40wt% of soluble fraction in a 1:4 in volume THF-n-hexane mixed solvent and less than 60% insoluble fraction in THF.
