Abstract
Silicone block polymers are obtained by cohydrolysis of a both end reactive diorganopolysiloxane and a silane or a partial hydrolyzate thereof or curing a both end reactive diorganopolysiloxane and an organopolysiloxane at room temperature or elevated temperatures. They have improved flexibility, stain resistance, thermal shock resistance, and water repellency and are suitable to form hard coatings, moistureproof coatings and topcoats.
