  • Anti-snag finish soluble in non-aqueous solvents
    Patent number: 4171935
    Abstract: The snagging of a fabric is reduced by treating the fabric with an organic solvent solution of a copolymer of a hydroxyalkyl acrylate, an acrylonitrile, an alkyl acrylate, and acrylic acid. The organic solution is readily prepared by solution polymerizing the named monomers in an organic reaction solvent, such as a mixture of toluene and n-butanol, stripping the reaction solvent, and then dissolving the polymerized product in an organic application solvent such as perchloroethylene or 1,1,1-trichloroethane.
