Anionic ring opening polymerizationCopolymersε-caprolactoneβ-butyrolactonePoly(蔚-caprolactone)- block -poly(尾-butyrolactone) copolymers were prepared in two-step synthesis. Firstly, poly(蔚-caprolactone) (PCL) was obtained by anionic ring-opening polymerization of CL initiated with anhydrous KOH ...
( III ), poly[1-methyl-sila- cis -pent-3-ene]( IV ), and poly[1-phenyl-1-sila- cis -pent-3-ene]( V ) were prepared by bulk anionic ring opening polymerization of the corresponding 1-silacyclopent-3-enes, at room temperature by use n -butyllithium or t -butyllithium and HMPA ...
The polymerization features of the polymerization of heterocyclic monomers using anionic or coordinated anionic type initiators are examined. The chemical and configurational structure of initiating ...
In this context, we have already found the anionic ring-opening polymerization of 1, 1,2,2-tetramethyl- l ,2- disilacyclopentane and -hexane. 2 It is then interesting to investigate a substituent effect on this polymerization. We here describe the anionic ring-opening polymeriza- tion of 1...
