Abstract:

The new composition 4,4-bis3-ethynylphenoxydiphenylsulfone is prepared by the nucleophilic displacement reaction of m-hydroxy-phenyl acetylene with various disubstituted diphenylsulfones. The composition is useful as a composite resin and also as a reactive plasticizer for polysulfone thermoplastic resins. A reactive plasticizer is a material that remains fluid and acts as a plasticizer during early stages of fabrication and then polymerizes to a rigid resin. Author
