摘要:
The present invention relates to new block copolymers of chemically modified polyolefins and thermoplastic polyurethanes, copolyesters or copolyamides a method for the preparation of said block copolymers and their use for compatibilizing blends of polar and non-polar thermoplastic elastomers. The block copolymers according to the present invention can further be used for promoting the adhesion of thermoplastic elastomers onto various polar engineering resins.
摘要:
Thermoplastic elastomers having improved surface properties are provided by incorporating a copolymer of a functionalized polyolefin and a polyamide into a thermoplastic elastomer selected from (A) (a) a thermoplastic polyolefin homopolymer or copolymer, and (b) an olefinic rubber which is fully crosslinked, partially crosslinked or not crosslinked, and optionally (c) common additives; (B) (a) a block-copolymer of styrene/conjugated diene/styrene and/or its hydrogenated derivative, optionally compounded with (b) a thermoplastic polyolefin homopolymer or copolymer and/or (c) common additives and (C) any blend of (A) and (B). The invention further relates to a process of making these modified thermoplastic elastomers, their use and shaped articles comprising them.

摘要:
A low polyphosphate or a polyphosphate free liquid heavy duty laundry detergent composition comprising a suspension of an alkali metal alginic acid builder salt in liquid nonionic surfactant. The laundry detergent composition comprises a nonaqueous liquid nonionic surfactant containing a stable suspension of an alkali metal alginic acid builder salt.
摘要:
Solutions of VCl.sub.4 in inert organic solvent are stabilized by incorporation of decomposition retardants being halogenated organic compounds having at least two halogen atoms attached to the same carbon atom and activated by adjacent electron donor groups or carbon-carbon double bonds. One of the especially preferred stabilizers is butyl perchlorocrotonate. The solutions are useful in polymerization processes.
摘要:
A liquid heavy duty laundry detergent composition comprising a suspension of builder salt in liquid nonionic surfactant. To improve dispensibility in automatic washing machines, the composition contains as a viscosity and gel controlling agent an alkylene glycol monoalkyl ether, especially diethyleneglycol monobutyl ether.
摘要:
Polymeric compositions and methods of making and using such compositions are provided. The compositions incorporate at least one component that is a polymer including propylene-derived units and at least one component that is a styrenic block copolymer. The polymeric compositions are found to have desirable elastomeric properties while at the same time exhibiting beneficial processability characteristics. The unique combination of processability and performance attributes result in the polymeric compositions useful in a variety of applications such as films, fibers, woven and non-woven fabrics, sheets, molded objects, extruded forms, thermoformed objects, and all products made from such application materials.
