STUDIES ON THE UV-CURING OF UNSATURATED POLYESTER/POLYEPOXY RESIN BLOCKED COPOLYMER RESIN
The UP-PER-UP blocked copolymer was prepared by the reaction of unsaturated polyester(UP)and polyepoxy resin(PER)under suitable conditions.The modified photosensitive resin was formed after the addition of the active monomers into the copolymer.The UV-cured process of the resin was investigated by means of FTIR spectrum and the properties of the UV-cured coat were characterized in terms of TG/DTA and other analysis.The resuIts indicated that the UV-cured resin showed the advantages of both unsaturated polyester resin and polyepoxy resin.The base-resistant ability
thermostability and surface hardness of the resin were greatly improved.The volume shrinkage of the sample was lowered from 7% to 0.8% and the adhesion power on substrate was increased. Thus the applications of unsaturated polyester resin were widely promoted.
