    摘要: Nitrogen-containing organopolysiloxanes which may also contain crosslinkable reactive groups are easily prepared by reaction of an alkoxy-functional oligosilane containing methylene linkages between silyl groups and nitrogen with organopolysiloxanes condensable therewith. The nitrogen may be quaternized if desired. The chain amino nitrogens can subsequently be quaternized if desired. Uses for the products include single component crosslinkable compositions.

    摘要: Siloxane-urea copolymers are easily prepared by reacting a bis- or poly[azasilacyclopentyl]-terminated compound with a hydroxyl-functional compound followed by reaction with di- or polyisocyanate. When a bis[hydroxyl]-functional compound is used, the resulting polymer may be reacted with additional di- or polyisocyanate, optionally in the presence of additional isocyanate-reactive compounds such as chain extenders.

    摘要: Non-blocking polymer pellets are produced in spherical or nearly spherical form by introducing molten polymer directly from a polymerization reactor into a coolant and pelletizing just prior to, simultaneously with, or immediately following entry into the coolant such that residual heat allows the polymer pellets to change their shape to eliminate sharp corners, particularly cylindrical shapes, and assume a spherical-type morphology.

    摘要: Amino group-containing organosilicon compounds containing no or only a small fraction of Si-bonded hydroxyl groups are prepared by preparing an organosilicon compound containing amino groups and Si-bonded hydroxyl groups by equilibration in the presence of an equilibration catalyst, and reacting the resultant product with a cyclic silazane. The products are particularly useful as a monomer or macromere for the preparation of high molecular weight organic polymers containing organosilicon blocks.
