Abstract
Polyester compositions having a fast rate of crystallisation comprising: a) 95-99.5% by weight of a polyester resin obtained by the condensation of a dicarboxylic aromatic acid with a C2-C4 alkylene glycol, b) 0.5-5% by weight of at least one nucleating agent comprising a styrene-maleic anhydride copolymer imidised so as to have a nitrogen content of between 0.5 and 4.5% by weight and converted into a salt with an alkali base in such a way as to have an alkali metal content of between 1 and 7% by weight.
