Abstract
A method for increasing the rate of polymerization of 2-octyl cyanoacrylate, or the rate of copolymerization of 2-octyl cyanoacrylate and a tri-telechelic star polymer comprising polyisobutylene terminated with cyanoacrylate groups (Ø(PIB-CA)3) to form a co-network, is provided. The method comprise initiating the polymerization of 2-octyl cyanoacrylate, or the copolymerization of 2-octyl cyanoacrylate and a tri-telechelic star polymer comprising polyisobutylene terminated with cyanoacrylate groups (Ø(PIB-CA)3) to form the co-network, with an initiator selected from the group consisting of cyclic tertiary aliphatic amines optionally dissolved in a non-aqueous solvent. The cyclic tertiary aliphatic amines are selected from the group consisting of azabicyclo[2.2.2]-octane (ABCO), and 1,4-diazabicyclo[2.2.2]-octane (DABCO).
