Photopolymerization of Polyether-polyurethane and Properties of the Products
Abstract:
Two chain extenders DTH and DTHM (prepared from diethanol amine, toluene diisocyanate and 2-hydroxyethyl acrylate/2-hydroxyethyl methacrylate, respectively) containing acryloyl and methacryloyl group were synthesized. The pre-polymer prepared by reaction of DTH or DTHM with polyether-polyurethane was photopolymerized to give a flexible material. The linear relation was found between the Shore hardness and the methacryloyl group content in the above photo-crosslinked polymer products. The contribution of polymer compositions to the hardness, flexibility and resolution power of the photosensitive materials has been investigated. The results provided for the further preparation of developing solvents. The optimum exposure time for the different photosensitive prepolymer systems has been determined.
