Thermoplastic gel compositions that can be converted into thermoset gel compositions by exposure to radiation

摘要

Disclosed is a thermoplastic gel composition that can be fabricated into an article, such as an air freshener or a gasket, and then be converted into a thermoset gel composition by exposure to radiation. The thermoset composition has better slump resistance at high temperatures compared to the thermoplastic composition. Prior to irradiation, the composition is a thermoplastic and so it can be easily mixed and formed into an article. Also disclosed are novel block copolymers.
