In order to provide Scientific basis for improving the property of polyester fibre the in fluential factors of reaction of free radical graft coplymerization of polyester fibre were introduced.

The preparation methods of macromolecular monomer and the technologies preparing copolymers with uniform side chains by free radical copolymerization of macromolecular and small molecular monomers were reviewed.

The analyzed results of FTIR and DSC, research of rheological changes respectively show that the radical copolymerization has happened among the monomers, and latexes are pseudoplasticity and have good sta.

An acrylic resin was synthesized by the radical copolymerization with methyl methacrylate (MMA), butyl acrylate (BA) and methacrylic acid (MAA) monomers in solution using benzoperoxide as initiator.

The free radical copolymerization of hydroxypropyl methacrylate HPMA(M1) and N-(11-carboxyunde-cyl) maleimide CUMI(M2) was carried out with benzoyl peroxides(BPO) as an initiator in toluene at 80℃.

The "living" and controlled radical copolymerizations of β-pinene with AN,MA,nBA and NPMI were achieved via the reversible addition-fragmentation transfer (RAFT) technique,at a low β-pinene/PVM feed ratio of 10/90.

Hydrophobically associating cationic polyacrylamide (PADO) was prepared by the free micellar copolymerization of acrylamide(AM),dimethyldiallylammonium chloride(DMDAAC) and octadecyl acrylate(OA) in aqueous solutions,initiated by the redox initiation.

Fluorocarbon-modified cationic polyacrylamide(FPAD) was prepared by free micellar copolymerization of acrylamide(AM),methacryloxyethyl trimethylammonium chloride(DMC) and dodecafluoroheptyl methacrylate(DFMA),initiated by redox initiation.

Hydrophobic associative cationic polyacrylamide flocculant was prepared by free micellar copolymerization of acrylamide (AM), dimethyldiallylammonium chloride (DMDAAC) and octadecyl acrylate (OA) in the aqueous solutions,initiated by redox initiation.
