ABSTRACT:
A molding is produced by thermoplastic shaping of at least one partially crystalline polymer which comprises, exclusively, polymerized units of vinylidene fluoride and other fluorine-containing monomers which contain only one C.dbd.C double bond, contains 20 to 50% by weight of polymerized units of vinylidene fluoride and has a melt index of at least 1 g/10 min at 250.degree. C. and 11 kg load, without addition of substances which contain polymerizable double bonds, and the molding is subsequently treated with a minimum dose of 50 kGY of ionizing rays at a minimum dose rate of 2 Gy/s. Moldings are thus obtained in a simple manner which have good mechanical and chemical properties and exhibit no discoloration.
