A shape memory elastic body.

摘要

A shape memory elastic body which comprises a reaction product obtained by reacting a composition comprises 100 weight parts of ethylene polymer, 1 - 400 weight parts of organopolysiloxane having a viscosity higher than 1,000 CS at 23 DEG C and expressed by Formula (A) <CHEM> (where R<1> is an unsaturated aliphatic group, R<2> is an unsubstituted or a substituted monovalent hydrocarbon group containing no unsaturated aliphatic group, 0<a<1, 0.5<b<3, and 1<a+b<3), 0.01 - 30 weight parts of a hydrocarbon compound expressed by Formula (B) CH2=CH(CH2)cCH=CH2 (B) where c is an integer of 1 - 30), and 0.005 - 0.05 wight parts of an organic peroxide, and which has a melt index equal to or higher than 0.001.
