Abstract

PURPOSE:To form polymer of high strength and high modulus and improve formability, by using polyester type polymer obtained by ester formation method which makes to react the organic monomer compound having the functional group forming the repeating unit. CONSTITUTION:The polyester type polymer composing the repeating unit with those shown in formulasI-IV (in formulas, a=0.30-0.50, b=0.05-0.40, c= 0.10-0.45, d=0-0.40, a b+c and a+b+c+d=1.0, R: bivalent radical) and having flow birefringence at the higher temperature than the flow temperature and under the shearing velocity 10sec<-1> or lower is used. Carboxylic acid radical, hydroxyl radical, ester radical, acyloxy radical, acid halogenide etc. are preferable as the functional radicals of the organic monomer compounds which form the repeating units.
