<p>Compositions comprising (i) thermoplastic polyester of aliphatic diol, and dicarboxylic acid, at least 95% mole of said acid being terephthalic acid and (ii) inert particulate nucleating agent further contain, as a crystallization promoter, (iii) oligomeric polyester of organic dicarboxylic acid having 2 to 8 carbon atoms and organic polyol and having a Flory Interaction Patameter with said polyester below or equal to 0.2. The compositions are useful moulding compounds, the crystallization promoter enabling crystalline moulded products to be obtained at low mould temperatures. Moulding processes of the invention are carried out at less than 100 DEG C mould temperatures.</p> |
