Document Type and Number:
WIPO Patent Application WO/2012/026501
Kind Code:
A1
Abstract:
Provided are a thermoplastic polymer composition with excellent flexibility, mechanical properties, moldability, and, in particular, heat resistance, and capable of being adhered at low temperatures (e.g., 190°C or less) to ceramic, metal, or synthetic resin, and a molded article formed by using said thermoplastic polymer composition. Specifically provided is a thermoplastic polymer composition containing 1-100 parts by mass of a polyvinyl acetal resin (B) and 5-100 parts by mass of a polar group-containing polypropylene resin (C) per 100 parts by mass of a thermoplastic elastomer (A) that is a block copolymer, or a hydrogenated product thereof, containing a polymer block with an aromatic vinyl compound unit and containing an isoprene unit, a butadiene unit, or an isoprene/butadiene unit with a total amount of 40 mol% or more of 1,2-bonds and 3,4-bonds.
