A series of poly(butyl methacrylate co (4 vinyl)pyridine)s with varied molecular weight and 4 vinyl pyridine content were synthesized using free radical copolymerization, and the gas permeation behaviors in copolymer membranes were measured using a low vacuum permeation apparatus .

Preparation of 2-vinylpyridine from 2-picoline;

Study on the Process of By-product 2-Picoline to 2-Vinylpyridine;

The synthesis of well defined and monodispersed narrow molecular weight distributed poly(2-vinylpyridine)-poly(methyl methacrylate) diblock copolymers (P2VP-b-PMMA) was carried out via living anionic polymerization initiated by n-BuLi in THF at ?78℃.

STUDIES ON THE PREPARATION OF STRONG ACIDIC-WEAK BASIC AMPHOTERIC ION EXCHANGE FIBER I. the grafting copolymerization of styrene and 4-vinylpyridine onto polypropylene fiber;

The catalytic activity of poly(styrene-crylicacid)(PSAA) supported neodymium chloride(NdCl_3) complex for the copolymerization of styrene and 4-vinylpyridine was studied.

Using styrene,4-vinylpyridine,acrylamide and DMC as raw materials,a family of dispersants with different anchors was synthesized by solution radical polymerization.

Coordination Process and Complex Structure between Poly(4-vinylpyridine) and Cu(Ⅱ) Ion;

A new polymeric complex,[(P4VP)Pt(C^N^N)]Cl,has been synthesized by the reaction of poly(4-vinylpyridine)(P4VP) with [Pt(C^N^N)Cl](HC^N^N=6-(4-methylphenyl)-2,2′-bipyridine),in which the Pt-Cl bond is replaced by pyridine group in P4VP.

Theoretical studies on stilbazoles have been carried out using density functional theory (DFT) at B3LYP/6-31G*, 6-31G**, 6-31+G* level to obtain optimized equilibrium structure.
