PROBLEM TO BE SOLVED: To provide a composition comprising polyolefin and poly-organosiloxane, that is excellent in heat stability and physical/mechanical property.SOLUTION: Provided is a composition comprising a polyolefin and a poly-organosiloxane in which at least 50 mol% of the siloxane units is D unit and that contains at least one unsaturated group, and in which the unsaturated group is a group having a formula of -X-CH=CH-R"(I) or -X-C≡C-R"(II) (X has an electron-withdrawing effect against -CH=CH- bond, or -C≡C- bond, and/or represents a divalent organo-bond containing an aromatic ring or an additional olefin double bond or an acetylene unsaturation, and the aromatic ring or the additional olefin double bond or the acetylene unsaturation is conjugated with the olefin unsaturation of -X-CH=CH-R" or the acetylene unsaturation of -X-C≡C-R", and also R" represents a group having an electron-withdrawing effect against hydrogen or -CH=CH- bond, or -C≡C- bond.). |
