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.

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

The hydrolytic depolymerization of polyethylene terephthalate (PET) under microwave irradiation is studied by differential scanning calorimetry(DSC) and Thermogravimetrical analysis (TGA).

The hydrolytic depolymerization of Polyethylene terephthalate (PET)and polybutylece terephthalate (PBT) under microwave irradiation is studied in this paper.

AM/AA/AMPS copolymer was prepared with micellar polymerization and post-hydrolysis procedures using acrylamide(AM),acrylic acid(AA) and 2acrylamido-2-methyl-1-propane sulfonic acid(AMPS) as raw materials.

An orthogonal test study of posthydrolysis process of hydrophobic associative polyacrylamide

Using acrylamide as monomer and by homopolymerization posthydrolysis procedure,the polyacrylamide with relative super-high moleculer weight is synthesized for oil driving in oil field.

The homopolymerization posthydrolysis of acrylamide initiated by a proper combined system is studied, then super high molecular weight polyacrylamide is obtained by using such an initiation system in aqueous solution, with molecular weight 25×10 6, hydrolytic degree can be adjusted between 20% and 30%, filter rate<1.
