RESIN COMPOSITION INCLUDING ETHYLENE-PROPYLENE BLOCK COPOLYMER, ETHYLENE-PROPYLENE RUBBER AND STYRENE- BASED ELASTOMER OR UNSATURATED CARBOXYLIC ACID- MODIFIED POLYBUTADIENE

摘要

ABSTRACTA resin composition having improved coating propertieswhich comprises (A) 67 to 91% by weight of an ethylene-pro-pylene block copolymer and (B) 33 to 9% by weight of an ethylene-propylene rubber having a Mooney viscosity (ML1+4, 100°C) of18 to 34 and, if necessary, (C) 3 to 15 parts by weight of anunsaturated carboxylic acid-modified polybutadiene or astyrene-based elastomer per 100 parts by weight of the totalof Components (A) and (B). The resin composition has excellentflowability and coating properties. A mold produced from theresin composition can be uniformly coated with a paint withouteither special pretreatments or a degreasing treatment. Thesecharacteristic features are improved in the composition com-prising Components (A), (B) and (C).
