Abstract : the preparation conditions of unsaturated polyester ( up ) resins modified by pet were introduced in this paper . the copolymerization mechanisms of the synthesis of up resins from cis - and trans - anhydride were researched . the relationship between the modified resins activities and the structure of unsaturated acids were also discussed . the reason for the differences of the exothermal curves of the two resin systems was that the activity of the cis - and trans - unsaturated bonds was different from each other
