Thermoplastic molding composition scan be advantageously used in hydrofluoro olefin containing areas, comprising components A, B, C and, D: 10 to 35 wt.-% ABS graft rubber A obtained by emulsion polymerization, 50 to 75 wt.-% SAN copolymer B, 4 to 20 wt.-% copolymer C from ethylene and C.sub.1-C.sub.6-alkyl(meth)acrylate, and 4 to 20 wt.-% ABS graft rubber copolymer D obtained by mass polymerization.

A synthetic polyisoprene copolymer is manufactured by stirring a synthetic polyisoprene rubber latex under the heating condition of 50 C. or higher, purifying the latex by centrifugation, adding a vinyl monomer to the purified synthetic polyisoprene rubber latex obtained and graft-copolymerizing the vinyl monomer. The synthetic polyisoprene copolymer is a copolymer in which a vinyl monomer is graft-copolymerized on the surface of synthetic polyisoprene particles, and which has a nanomatirx structure in which the synthetic polyisoprene rubber particles are dispersed in a continuous phase having a thickness of from 1 to 100 nm formed by graft chains in a phase-separated state.

Core-shell copolymers are described, along with methods of making same, which provide improved adhesion and cohesion when used as additives in pressure sensitive adhesives. The core-shell polymers contain copolymers with ureido functionality in the shell region only, while the core region is substantially free of ureido functionality.

The present invention relates to a cross-linked porous membrane from hydrolysis of ester-containing side chain and a preparation method thereof. Firstly, membrane material is obtained through copolymerization of four monomers including butyl methacrylate, styrene, sodium sulfonated styrene and vinylbenzyl chloride. In membrane formation, a small amount of lithium chloride micromolecule porogen is added and cross-linked by using tetramethyl hexamethylene diamine to prepare a nanoscale dense membrane through hydrolysis under the alkaline condition. Through the characteristic of hydrolysis of a butyl ester side chain in the polymer under the alkaline condition, the space originally occupied by the butyl ester in the hydrolyzed membrane is vacated; and after hydrolysis, with the appearance of carboxylic acid ionic conduction groups, a large quantity of ester bonds is hydrolyzed, so that the patency of ion transfer channels in the membrane is enhanced. Thus, ionic conductivity of the membrane is greatly enhanced. The nanoscale porous membrane prepared by the present invention not only has good selectivity and battery performance, but also reduces the preparation cost of the membrane to a great extent, and is suitable for application in all vanadium flow batteries.
