Abstract

A moulding composition is based on polyethylene terephthalate (PET) and contains as additives polycaprolactone with a number average molecular weight greater than 10,000 and a nucleant for crystallization of the PET. The composition can also contain a reinforcing fibre, such as glass, and a plasticizing additive, which may be, for example, a lower molecular weight polycaprolactone, or a plasticizer such as dibenzyl adipate.
