3 results about "Divinyl benzene" patented technology

A styrene-series ion exchange resin (homogeneous styrene copolymerized resin) is prepared through under existance of styrene trigger polymerizing to obtain "seeds", and suspension copolymerizing reaction between said seeds, styrene and divinyl benzene in water-phase medium under the action of trigger. Its advantages are high strength and exchange performance, long service life, and high output rate.

The invention discloses a partially hydrogenated styrene-b-butadiene-divinyl benzene/isoprene random copolymer as well as a preparation method and application thereof. The polymer material is obtainedby partially hydrogenating a polymer with a structural formula of Sx-b-(By-Dg/Iz), Sx is a styrene homo-polymerization block, and By-Dg/Iz is a butadiene, isoprene and divinyl benzene random copolymerization block. The polymer material has the advantages of good mechanical property, strong ageing resistance, good heat resistance, low compression deformation, long continuous tensile time, capability of being used for vulcanizing double bonds, long chain branching, wide molecular weight distribution and the like, and is particularly suitable for being used as a window sealing material used outdoors.
