The paper presents the results of a study of the plasticizing effect of oligomers
based on 4.4'-dihydroxydiphenyl and 4.4'-dichlorodiphenylsulfone, as well as
4.4.-dihydroxydiphenylpropane (Diane) and 4.4'-dichlorodiphenylsulfone on polyphenylene
sulfone and highly filled composites on its basis. It was established that these oligomers are
quite effective plasticizers during processing, increasing the melt flow rate and retaining
elastic-strength properties at concentrations up to 20%. At the same time, they have high heat
resistance and the necessary compatibility with the matrix polymer.
Keywords: polyphenylene sulfone, composite material, glass fiber, carbon fiber, plasticization, oligomer |
