PURPOSE:To obtain the subject composition resistant to staining, giving a foamed material resistant to the deterioration of appearance and suitable as a cushioning material for building. etc., by compounding a crosslinkable and foamable composition with a reaction product of an ethylenic resin, a silicone having vinyl group and a hydrocarbon containing diene. CONSTITUTION:The objective composition is produced by compounding (A) a crosslinkable and foamable composition satisfying the formula I (Tp is 10min half-life temperature of organic peroxide; Tf is foaming temperature) and com posed of 100 pts.wt. of an ethylenic resin, 1-30 pts.wt. of a foaming agent and 0.2-10 pts. of an organic peroxide as a crosslinking agent with (B) >=0.1 pts.wt. of a reaction product derived from 100 pts.wt. of an ethylenic resin, 0.01-300 pts.wt. of an organopolysiloxane of formula II (R<1> is aliphatic unsaturated group; R2 is univalent hydrocarbon group free from aliphatic unsaturated group; 0<x<1; 0.5<y<3, 1<x+y<3), a hydrocarbon compound of formula III (n is 1-30) and 0.001-3 pts.wt. of an organic peroxide. |
