摘要:
Cellulosic materials such as paper are internally sized by treating fibers of the cellulosic material, e.g., paper pulp, with a copolymer of an Alpha , Beta -ethylenically unsaturated hydrophobic monomer and an ammoniated Alpha , Beta ethylenically unsaturated carboxylic acid and a reaction product of epihalohydrin and ammonia. Internal sizing of the cellulosic material by this method can be carried out under acidic, neutral or basic conditions.
