Abstract:
Polychloroprene rubber (CR) has been used for decades as the base polymer in rubber based adhesive applications: for example in the construction, furniture and upholstery industries. The conventional method of preparing the polychloroprene polymer for formulating and milling with other critical ingredients and then presenting final adhesives for applications has been in solvent diluted fluids. Even though polychloroprene is well known as the balanced material in rubber adhesives, adherends such as plasticiser incorporated synthetic leathers, Ethylene vinyl acetate co-polymer cannot be adhered by CR only. A graft polymer of MMA with CR could be widely used because of its plasticizer resistance. This paper presents the current progress and technology of a grafting procedure to formulate adhesives, using solvent based polychloroprene grades. The technology for CR grade adhesive applications is described along with comparisons with different chemical ingredients and solvent systems.
