4.The water-soluble tripolymer of maleic anhydride(MA), sodium allylsufonate(SAS)and acrylamide(AM) was prepared with water as solvent and persulfate as initiator.
5.Synthesis of polyethenoxyether phosphate using polyethenoxyether as initiator and using phosphorus pentoxide as parkerizing reagent, and its application were studied.
6.The cationic ring-opening polymerizations of epoxide based monomers were studied using tris(2-hydrooxyethyl) isocyanurate(THEIC) as initiator and trifluoroboron plus ether complex system as catalyst.
