Abstract
A sheet including an olefin thermoplastic elastomer obtainable by dynamically heat-treating 100 parts by weight of a mixture of 40-90% by weight of (A) an olefin polymer rubber having a Mooney viscosity at 100.degree. C. (ML.sub.1+4 100.degree. C.) of 5-100 and substantially free from unconjugated diene and 60-10% by weight of (B) an olefin polymer in the presence of 0.005-0.5 part by weight of an organic peroxide and 0.05-4 parts by weight of N,N'-m-phenylenebismaleimide or divinylbenzene. Said sheet is excellent in light resistance and thermal aging resistance. A laminate including said sheet and a use thereof are also provided.
