ABSTRACT:
A shaped article made of a polymeric composition comprising as the essential component a saturated linear polyester or polyamide comprising a structural unit of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are same or different and each represents a monovalent organic group such as a monovalent aliphatic, alicyclic or aromatic group having one or more carbon atoms (preferably 1 to 20 carbon atoms) and m and n are each an integer of 0 to 3 in an amount of 0.01 to 50 moles per 100 moles of the total ester or amide linkages in the molecule of the polyester or polyamide is irradiated with actinic rays so that chain-linking takes place between or among the molecules of the polyester or polyamide, whereby the physical and chemical properties of the shaped article are favorably enhanced.
