    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.

    摘要: One-component, moisture curing compositions which exhibit rapid curing, even with exceptionally low levels of catalyst or with no catalyst at all, can be formulated from alkoxysilane-terminated polymers having alkoxysilane groups bonded to an electronegative, free electron-pair-containing heteroatom via a methylene linking group. Polymer blends containing the alkoxysilane-terminated polymers exhibit rapid cure, even at room temperature, and allow the use of nitrogen containing components such as adhesion promoters.

    摘要: Primary aminoalkyl-terminated organopolysiloxanes are prepared simply and in high yield by reaction of hydroxyl-terminated organopolysiloxanes with an aminoalkyl-and alkoxy-functional silane. The primary aminoalkyl-terminated organopolysiloxanes are particularly useful as polymer intermediates in the preparation of polymers such as polyimides and polyureas.
