  • Method for externally sizing fibrous materials
    Patent number: 6482886
    Abstract: Fibrous product is externally sized by applying to the material a basic aqueous dispersion of an interpolymer of an ethylenically unsaturated monomer and an ethylenically unsaturated carboxylic acid comonomer. 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.
