Abstract

PURPOSE: To provide a composition having inproved mechanical strength (impact strength), by blending polyester resin consisting mainly of polyethylene terephthalate with urethane-modified epoxy resin.
CONSTITUTION: Urethane-modified epoxy resin A (pref. epoxy eq. 200W10000, urethane-modified 2W70% by weitht) is produced by the reaction of an epoxy cpd. with urethane prepolymer having isocyanate end gp. which is obtained by reacting polyisocyanate with active hydrogen containing compound having molecular weight in the range about 200W5000. Then 100 parts by weight of polyester resin having polyethylene terephthalate repeating unit of above 80mol% is blended with from 0.5W20 parts of the above modified epoxy resin to produce the desired resin compsn.
