Stain-resistant, polyamide textile substrates treated with compositions comprising hydrolyzed ethylenically unsaturated aromatic/maleic anhydride polymers and processes for their preparation. The treated substrates possess stain resistance that is as good as or better than do previously known stain-resist treated substrates but do not suffer from yellowing to the extent that previously known treated substrates do.

Stain-resistant aromatic/maleic anhydride polymers

A blend of refrigerant with at least one fluorinated hydrocarbon, in which the weight ratio of fluorine-to-carbon is from about 0.5 to 5, and which has an SUS viscosity at 100.degree. F. of at least 50 and a pour point of less than about -20.degree. C. is disclosed for use in compression refrigeration.
