摘要:
Thermotropic fully-aromatic polyesters which contain radicals of 3,4'- and/or 4,4'-dihydroxybenzophenone in addition to radicals of p-hydroxybenzoic acid, iso- and optionally terephthalic acid, hydroquinone and/or 4,4'-dihydroxydiphenyl, have good rigidity and toughness and yet are easily processible.
