Abstract:
The present invention provides a polyurethane which is non-sticky, exhibits superior handling properties and superior moldability, and has superior adhesive properties with silicones even if a surface activation treatment is not carried out beforehand. The polyurethane of the present invention contains polyol units and organic polyisocyanate units. The polyol units contain an alkenyl group-containing organopolysiloxane structure in an amount ranging from 0.01 to 20% by weight with respect to the weight of the aforementioned polyurethane.
