Novel polyesters prepared from mixture of hydroquinone and bisphenols |
摘要 |
A linear copolyester having a reduced specific viscosity of at least 0.5 is prepared from terephthalic or isophthalic acid, a bisphenol and hydroquinone. The ester unit derived from terephthalic or isophthalic acid and hydroquinone is contained in the copolyester in a proportion of 5 to 35 mole%. The copolyester has superior crack resistance, thermal stability, transparency and chemical resistance.
