Functionalized chain extended initiators for anionic polymerization

A process for removing a protecting group from a polymer. Protected functional groups of a polymer may be deprotected by treating the polymer in the presence of an acid catalyst, including organic acids, mineral acids, heterogeneous acid systems, Lewis acids, and fluoride ion sources.

Selected deprotection of protected functional polymers

Protected amine anionic polymerization initiators useful in the preparation of polymers having a protected amine functional group. The initiators are very soluble in hydrocarbon solvents.

Amine anionic polymerization initiators and functionalized polymers

Deprotection of protected functional polymers

A process for the preparation of hydrocarbon solutions of monofunctional ether initiators of the following general structure:
