<p>Polyesters of 2,6-naphthalenedicarboxylic acid having a reduced crystallization rate obtained by the polycondensation of: a) at least one diol consisting essentially of a C2-C4 alkylene glycol; b) a diacid consisting essentially of 2,6-naphthalenedicarboxylic acid, possibly substituted with halogens or with C1-C4 alkyl radicals, or one of its derivatives; c) 0.1-5% in moles, with respect to the total sum of the acid components, of at least one dihydroxyterminated polyalkylenglycol having an average molecular weight of between 500 and 5000.</p> |
