Study on properties of nylon 6 prepared via anionic slurry polymerization;

The isotactic polypropylene prepared under the supercritical conditions was compared with that obtained by a conventional slurry polymerization with respect to the isothermal crystallization kinetics by Perkin Elmer differential scanning calorimetry(DSC) and Nikon E600 optical polarimeter(OP) with on-line hot stage,respectively.

The Cp 2ZrCl 2/MAO catalyst was evaluated with ethylene slurry polymerization by pilot test.

Behavior of propylene slurry polymerization was investigated at 15 ℃ , 0.

Polar additives in anionic polymerization;

Octamethylcyclotetrasiloxane(D4)and N-(β-aminoethyl)-γ-aminopropylmethyldimethoxysilane(KH-792) were chosen to synthesize aminopolysiloxane by bulk anion polymerization,with KOH as catalyst,hexamethyldisiloxane(MM)used as end capping agent,and dimethyl sulfoxide(DMSO) utilized as accelerating agent.

We synthesized (SI)_4Si star-type block copolymer with styrene,isoprene and silicon tetrachloride as raw materials,tetrahydrofuran as molecular weight regulator,cyclohexane as solvent,and n-BuLi or naphthalene lithium as initiating agent by anion polymerization method with three steps.

Synthesis methods of PFPE are mainly anion polymerization of perfluoro-epoxide and photo-initiated oxidation of perfluoro-olefine.

This paper reviews various methods of synthesis of hydrophobically associating water-soluble polymers,including copolymerization of acrylamide with hydrophobic monomers(heterogeneous process,homogeneous process,micellar copolymerization,inverse microemulsion process,emulsion process without emulsifying agents and anionic copolymerization)and macromolecular reactions.
