Abstract
A method for a synthesis of a polymer containing multiple epoxy groups includes steps of: under protection of nitrogen or argon, with a photosensitive free radical initiator under an ultraviolet light irradiation, initiating a mixture of a dithiol compound and alkynyl glycidyl ether or other alkynyl-containing compounds to proceed a thiol-yne polymerization, so as to obtain the polymer. The number of the epoxy groups is able to be adjusted through changing a type of a dithiol monomer, a mixing ratio of the dithiol monomer, and a mixing ratio between the alkynyl glycidyl ether and other alkynyl compounds. The present invention has advantages of: fast reaction, convenient process, easy post-processing, a large number of the epoxy groups, and adjustable and controllable content. The obtained polymer has a wide potential application in fields of coating, adhesive, ink, encapsulating material, resin for composite material, additive, high performance material, function material, and so on.
