Progress in synthesis of isoprene rubber by binary rare earth catalyst system based on rare earth chloride with neutral phosphates or phosphonates as ligand
The present situation of research & development of the catalysts for the synthesis of isoprene rubber,as well as types and characteristics of the binary rare earth catalyst systems was introduced with 19 references.The polymerization activity of rare earth chloride with neutral phosphates or phosphonates as ligand for isoprene polymerization was analyzed,and NdCl3·nP350 [P350 was di-(1-methyl-heptyl) methyl phosphonate] was discussed especially,which had a higher polymerization activity for isoprene polymer...
