Abstract
A process for making thin walled hollow polymeric articles or for forming a polymeric coating on a substrate, comprises contacting a suitably shaped former on a substrate to be coated with a solution of an amine-terminated prepolymer having a functionality of at least 2 in an organic solvent to form a coating on the former or substrate, drying the coating on the former or substrate, then contacting the coating on the former or substrate with a solution of a polyfunctional curing agent which is capable of reacting with the amino end groups of the prepolymer to cause chain extension and/or cross-linking of the latter.
