Method for externally sizing fibrous materials

method of externally sizing a fibrous material which comprises applying to the material a basic aqueous dispersion of an interpolymer of an ethylenically unsaturated monomer and an ethylenically unsaturated carbonxylic acid. The preferred dispersions which have lower initial viscosities provide disp...

Zusammenfassung:	method of externally sizing a fibrous material which comprises applying to the material a basic aqueous dispersion of an interpolymer of an ethylenically unsaturated monomer and an ethylenically unsaturated carbonxylic acid. The preferred dispersions which have lower initial viscosities provide dispersion/starch dilute solutions with higher viscosities and improved external sizing effectiveness. Resulting fibrous products are adequately sized and exhibit excellent printability and strength properties. method of externally sizing a fibrous material which comprises applying to the material a basic aqueous dispersion of an interpolymer of an ethylenically unsaturated monomer and an ethylenically unsaturated carbonxylic acid.
