Abstract
An increase in the molecular weight of a polyamide or recycled polyamide can be achieved by blending said polyamide with a polyfunctional epoxy resin and a sterically hindered hydroxyphenylalkylphosphonic acid ester or half ester and heating the blend to above the melting point (glass transition temperature) of the polyamide.
