A novel synthetic strategy for hydroxyl-terminated polybutadiene containing high cis-1,4 contents based on a Ni(ii)-coordinated anionic initiating system

Abstract

In this study, novel hydroxyl-terminated polybutadiene (HTPB) with a high cis-1,4 content was developed using a tert-butyl dimethyl siloxy dimethyl propyl lithium (Li)–naphthenate nickel (Ni)–boron trifluoride (B) initiating system (Li–Ni–B).

“…respectively. 47,48 In order to test the efficacy of RDRP from Br-PB-Br as the macro-initiating site, the preparation of a series of PDMAEMAb-PB-b-PDMAEMA copolymers was attempted via recyclable alloy mediated RDRP (Scheme 1 and Table S1 †). A recyclable alloy mediated ambient temperature RDRP process was chosen for the triblock copolymer synthesis as this technique was recently successfully employed by our group for welldefined block copolymer synthesis.…”
