摘要： AN IMPROVED BONDING MATERIAL COMPRISING A HYDROLYZED SILOXANE AND A POLYMINE WHICH IS DISPERSIBLE IN THE SIOLOXANE. THE COATING MATERIAL IS PREFERABLY APPLIED TO GLASS FIBERS AT FORMING FROM AN AQUEOUS SOLUTION, AND THE COATED FIBERS ARE PREFERABLY USED TO STRENGTHEN A MAXTRIX RESIN WHICH IS FUSED WITH THE COATING MATERIAL SO THAT DIFFUSION OF THE POLYIMINE INTO THE MATRIX RESIN TAKES PLACE. COMPOSITES OF THE COATED GLASS FIBERS WITH MATIX RESINS THAT ARE REACTIVE WITH AMINE HYDROGEN HAVE GREAT STRENGTH.

摘要： A molding compound contains an uncured siloxane resin, a lead containing catalyst, and a silane or polysiloxane containing an appreciable amount of silanol or alkoxy groups. The molding compound is relatively stable at flow temperatures but cures rapidly at molding temperatures. The molding compound is used in the transfer molding of transistor housings.

摘要： THIS INVENTION RELATES TO CYCLOBUTANE DIOL POLYESTERSUBSTITUTED ORGANSILICON COMPOSITIOS CHARACTERIZED BY A POLYMERIC SEGMENT OR BLOCK THAT IS COMPOED OF RECURRING CYCLOBUTYLENE GROUPS LINKED TO EACH OTHER THROUGH CARBONATE LINKAGES (-OCOO-) OR DI(CARBONYLOXY)HYDROCARBYLENE LINKAGES AND THAT IS CHEMICALLY BONDED TO A SILICON ATOM. THE NOVEL COMPOSITIONS HAVE A SILICON-CONTAINING SEGMENT DERIVED FROM A SILANE OR A SILOXANE. IN THE LATTER CASE, THE COMPOSITION ARE BLOCK COPOLYMERS. THE COMPOSITIONS ARE STABLE TO HEAT AND LIGHT AND ARE USEFUL AS PROTECTIVE COATINGS, MOLDING ESINS AND ELASTOMERS.

摘要： TEXTILE MATERIALS ARE FINISHED BY TREATMENT WITH AN AQUEOUS BATH WHICH CONTAINS A POLYURETHANE PREPOLYMER HAVING FREE ISOCYANATE GROUPS WHICH IN TURN HAS BEEN OBTAINED FROM AN ORGANIC COMPOUND HAVING ACTIVE HYDROGEN CONTAINING GROUPS AND AN ORGANIC POLYISOCYANATE, AND AN ORGANO POLYSIOLOXANE HAVING A MOLECULAR WEIGHT OF TO ABOUT 25,000 AND CONTAINING AT LEAST TWO ACTIVE HYDROGEN CONTAINING GROUPS. THE ORGANO POLYSILOXANE IS REACTIVE WITH THE ISOCYANATO PREPOLYMER O THE TEXTILE SUBSTRATE IN ORGER TO GIVE THE TEXTILE MATERIAL A FULL PLEASANTLY SOFT, SUPPLY HAND AND REDUCE SUSCEPTIBILITY TO SOILING. ONE MAY USE POLYMERS OR COPOLYMERS PREPARED FROM VINYL OR DIVINYL MONOMERS IN THE AQUEOUS BATH ALONG WITH THE OTHER COMPONENTS.

摘要： BLOCK-COPOLYMERS OF APOLYURETHANE AND A POLYSILOXANE HAVING DIRECT SILICON TO NITROGEN LINKAGES, A METHOD FOR THEIR FORMATION AND ARTICLES FORMED THEREFROM. THE COPOLYMERS ARE FORMED BY A CONDENSATION TYPE REACTION BETWEEN REACTIVE TERMINAL GROUPS OF THE POLYSILOXANE AND THE URETHANE-AMIDE GROUPS OF THE POLYURETHANE. INASMUCH AS THE REACTION INVOLVES ONLY THE AMINO GROUPS OF THE POLYURETHANE, BOTH POLYETHER AND POLYESTER URETHANES MAY BE USED. THE PREFERRED BLOCK-COPOLYMERS ARE THOSE HAVING A MINOR PORTIONOF POLY(DIALKYLSILOXANE) SEGMENTS AND A MAJOR PORTION OF POLYURETHANE SEGMENTS. THESE COPOLYMERS ARE CHARACTERIZED BY A HIGH DEGREE OF BLOOD COMPATIBILITY AND CONSEQUENTLY, ARE USEFUL IN PROVIDING BLOOD CONTACT SURFACES FOR DEVICES USED FOR DIRECT IMPLANTATION INTO THE BODY OR FOR EXTRACORPOREAL CIRCULATION OF BLOOD SUCH AS CIRCULATORY ASSIST DEVICES INCLUDING AUXILIARY VENTRICLES AND INTRA-AORTIC BALLOONS, AND VARIOUS TYPES OF BLOOD PUMPS.
