Preparation of a Self-Crosslinking Resin System at Ambient Temperature

Abstract:

A reversible addition fragmentation chain transfer (RAFT) agent, 2-(dodecylthiocarbonothioylthio)propanoic acid (RAFT-1), was synthesized and characterized. Diacetone acrylamide and poly(ethylene glycol)methyl ether methacrylate were polymerized in the presence of RAFT-1 to give an amphiphilic polymer(RAFT-2). A very stable and narrowly-distributed emulsion was obtained by the micellization of the amphiphilic polymer in water. The self-crosslinking resin system was prepared by adding a crosslinker (adipic dihydrazide) to the prepared emulsion. Upon the evaporation of water of the emulsion, a tough and transparent crosslinked film was prepared, which had good water/solvent resistance and certain adhesiveness.
