Reactions of Living Polytetrahydrofuran with Amines V ‐ Tertiary Amine Terminated Polybutadienes; The Synthesis of Novel Ionically Linked Block Copolymers
Abstract:The reactions of mono‐ and difunctional tertiary amine ended polybutadienes with mono‐ and difunctional living cationic poly THF have been studied. It is shown that the reaction to form quaternary ammonium linking groups takes place rapidly in all cases, and AB. ABA, BAB and (AB) block copolymers have been prepared. The efficiency of the process is extremely high and the degree of conversion is essentially controlled by the efficiency with which the terminal tertiary amine groups can be introduced on to the po… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
