POLYMER PLASTICIZED WITH AROMATIC SULFONE OR AROMATIC SULFOXIDE AND CHARACTERIZED BY 1,3-IMIDAZOLIDINE-1,3-DIYL RING

摘要

Normally intractable polymers of the structure: ##STR1## wherein X is O or NH, provided at least one X is O, R is an organic moiety, such as poly(parabanic acids) are plasticized by composition with from 15 to 60 weight percent of an aromatic sulfone or aromatic sulfoxide such as diphenyl sulfone, diphenyl sulfoxide or dibutyl-4,4'-sulfonyl dibenzoate.
