PAPERS CONTAINING FLOC DERIVED FROM DIAMINO DIPHENYL SULFONE
摘要
This invention relates to papers made with floc containing a polymer or copolymer derived from a monomer selected from the group consisting of 4,4'diaminodiphenyl sulfone, 3,3'diaminodiphenyl sulfone, and mixtures thereof. Such papers have higher elongation-at-break and work-to-break (toughness) properties and exhibit less shrinkage at high temperatures than papers made with solely with poly (metaphenylene isophthalamide) floc.
