    摘要: Aminoalkyl-functional siloxanes are prepared efficiently by a continuous process in which a cyclic silazane and a hydroxyl-functional siloxane are fed continuously to a reaction zone, reacted in the reaction zone, and the aminoalkyl product and any unreacted starting materials are removed from the reaction zone. The process is effective even with hydroxyl-functional siloxanes having a very low weight percentage of hydroxyl groups.

    摘要: A method for the solvent-free, continuous production of organopolysiloxane/polyurea/polyurethane block copolymers involves reacting amino-functional siloxanes with polyisocyanates and organic polyhydroxy compounds. The organopolysiloxane/polyurea/polyurethane block copolymers produced by means of the inventive method are useful for numerous purposes, for example as elastomers, caulks, sealants, and films.

    摘要: Organopolysiloxane/polyurea/polyurethane block copolymer elastomers exhibiting improved physical properties are prepared by reacting diisocyanates with aminoalkyl-functional organopolysiloxanes containing substantially no cyclic siloxanes, prepared by reacting a cyclic silazane with a bis(hydroxy)-organopolysiloxane. Traditional hydroxyl and amino-functional chain extenders may be reacted as well, to produce a wide range of block copolymer elastomers.
