Synthesis of partly hydrolyzed branched polyacrylamide initiated by Cu(Ⅲ) complex ion through homopolymerization and cohydrolysis of acrylamide;

Through homopolymerization posthydrolysis process, the partially hydrolyzed polyacrylamide (PAM) with super-high relative molecular weight is synthesized by two-stage polymerization method and bifunctional initiator initiates the polymerization, and the effects of polymerization and hydrolysis technical parameters on the relative molecular mass are studied.

A series of hydrophobically associating water-soluble polymers poly(acrylamide/sodium acrylate/N,N-diallyl-N-tetradecylamine)(P(AM/NaAA/DiAC_14)) were prepared by way of co-hydrolysis with alkali before radical micellar copolymerization.

A series of twin-tailed hydrophobically associating water-soluble terpolymers poly (acrylamide/sodium acrylate/di-n-butylacrylamide)[P(AM/NaAA/DiC_4 AM)]were synthesized first by micellar copolymerization and then by co-hydrolysis with alkali.

The hydrolytic copolycondensation of phenyltriethoxysilane(PTES) and γ-aminopropyltriethoxysilane(APS) was carried out in such four reaction systems as the toluene/water/hydrochloric acid,the tetrahydrofuran/water/hydrochloric acid,the ethanol/water/ammonia and the sodium dodecyl sulfate/water/tetramethylammonium hydroxide.
