摘要:
A copolyester comprising: a dicarboxylic acid component comprising: (a) 80 to 99.5 mol% of units derivable from terephthalic acid or an ester forming derivative thereof, and (b) 0.5 to 4.5 mol% of units derivable from a phenylenedioxy diacetic acid or an ester forming derivative thereof; and a diol component
摘要:
A polyester obtainable by copolymerizing a dicarboxylic acid component (A) comprising: (a) 10 to 90 mol% of isophthalic acid or an ester forming derivative thereof; (b) 10 to 60 mol% of a phenylenedi(oxyacetic acid) of formula [I]: wherein R¹, R², R³ and R⁴ each independently represents a hydrogen atom, an alkyl group of 1 to 6 carbon atoms, an alkoxy group of 1 to 6 carbon atoms, a phenyl group, a chlorine atom, a bromine atom or a fluorine atom, or an ester forming derivative thereof; and (c) 0 to 45 mol% of a naphthalenedicarboxylic acid or an ester forming derivative thereof; and a diol component (B).
