coordination polymerization
2.The coordination polymer (EPU Pr 3+ ) was fromed by the reaction of praseodymium chloride with electropolyurushiol polymerization (EPU).
3.New Catalyst for Acetylene Polymerization——Scandium Compound and Aluminum Trialkyl Coordination Catalyst
4.INVESTIGATION OF THE HOMOGENEOUS SYSTEM BASED ON RARE EARTH COORDINATION CATALYST AND ITS STRUCTURE OF ACTIVE SPECIES Ⅰ. Polymerization of Butadiene in the Presence of (CF_3COO)_2 NdCl ·EtOH-Et_3Al
5.The polymerization of butyl methacrylate (BMA) is carried out by using Fe(acac) 3 Al(i Bu) 3 as a coordination catalyst. The effect of reaction temperature, time, solvent and catalyst concentration to BMA polymerization is studied.
6.Coordination polymer[EPU-Zn(Ⅱ)] was formed by the reaction of zinc diisopropoxide with electropolyurushiol polymerization. The structure and properties of EPU-Zn(Ⅱ) were characterized by AES,FT-IR, DMTA, TG-DTA and XPS . The results show that some crosslinkages are formed by coordination of electropolyurushiol with zinc(Ⅱ) in the coordination polymer.
7.POLYMERIZATION OF ACETYLENE BY COORDINATION CATALYSTS COMPOSED OF MULTICOMPONENT RARE EARTH COMPOUNDS-TRIETHYL ALUMINIUM-THIRD COMPONENT (Ⅱ)——La and Pr Coordination Systems of Different Ligands
8.It was shown that coordination catalysts of La, Pr, Nd, Eu, Gd, Er, Yb, Lu rare earth eight elements all have catalyties activities for the polymerization reaction of BMA.
9.Experimental results showed that the cation of the added salts combined either with water forming aquo-metal ions or with the anion of silicic acid forming coordination complexes and thus giving rise to two different effects on the rate cf polymerization of silicic acid: electrostatic and chemical reaction.
10.The Ln(TFA)32H2O-Al(i-Bu)3-I were used as catalyst for ring opening polymerization of epichlorohydin(ECH). It was found that coordination catalysts composed of Y, La, Pr, Sm, Eu, Tb, Dy, Ho, Er, Tm, Yb all have catalytic activities for the polymerization of ECH.
