Abstract
The present invention relates to a thermoplastic resin composition comprising (A) ionomer of ethylene/(meth)acrylic acid copolymer 60 to 96.7% by weight, (B) ethylene or alpha-olefin/glycidyl monomer copolymer 0.3 to 10% by weight and (C) propylene/alpha-olefin copolymer 3 to 30% by weight. The resin composition has excellent processability, workability, visual qualities, abrasion resistance, scratch resistance, surface hardness, stain resistance, heat resistance, etc, and is usable for building materials such as handrails, flooring materials and wall papers; car interior-exterior parts, toys, stationery, sundries, etc.
Claims11
