polystyrene resin
1.Therefore, in this paper, the new amino resin(PS-EDA and PS-TEPA) was preparedfrom acetylated polystyrene micro-beads, formaldehyde and tetraethylene pentamine(or ethylenediamine ) by Mannich reaction, which can substitute anion-exchange resinprepared from chloromethyl polystyrene resin and as immobilization support ofenzyme.
2.Hypercrosslinked polystyrene macroporous resin has been synthesized in nitrobenzene by one step. The resin has higher ratio surface (about 250 m~2·g~(-1)) and higher absorbability for phenol in water.
4.It is widely used in suspension polymerization of polystyrene (PS), expandable polystyrene (EPS), ABS resin, polymethyl methacrylate(PMMA) and styrene-arcylonitrile (SAN). It also can be used in suspension polymerization of polyvinyl chloride (PVC).
5.Polystyrene supporteo polyethylene glycol resin(PS-PEG-400 )with various PEG conten t was used as immobilized phase transfer catalyst for reactions of the addition of cyclohexenewith dichlorocarbene and N-butylation of acetanilide.
6.The purpose of this paper is to develop a new electroactive polymer with different kind partial sulfonated polystyrene(SPS) positive ion resin which using N-methyl-pyrrolidone (NMP) as the solvent, with initiated by benzoyl peroxide (BPO).
7.Polystyrene type strongly basic (type 1) anion exchange resin (30A) with high exchange capacity and macroprous structure was synthesized. Its physical and chemical properties approach to Amberlite IRA 900C.
