Product Application Of 1,4-Butanediol dimethacrylate CAS#2082-81-7

1,4-Butanediol dimethacrylate is an important crosslinking agent, which can be used as a crosslinking agent for rubber and plastics, a modifier for rubber and synthetic resins, an adhesive for acrylic sheets, and a plasticizer for glass fibers. It is widely used in injection moldings, rubber, optical plastics, adhesives, dental materials, wire and cable coatings, etc. At present, the preparation of 1,4-butanediol dimethacrylate is usually carried out by a reactive distillation ester exchange process in the presence of a catalyst and an inhibitor. The purpose of adding a catalyst and an inhibitor is to accelerate the reaction process and prevent polymerization during the reaction and distillation under the action of light and heat.
