    Abstract: The present invention relates to non-halogenated hydrocarbon polymeric compositions which impart durable stain resistance to fibrous substrates, particularly nylon containing articles. In addition, it relates to fluorine containing polymeric compositions which impart durable stain resistance to fibrous substrates as above. It relates also to processes in which such substrates are treated so as to impart durable stain resistance to them. It relates further to a manufacturing process for preparing the compositions of the invention.

    Abstract: Fibers containing free amino groups, and especially polyamide fibers, can be made resistant to certain stains, especially those resulting from food grade dyes, by contacting the fiber with a solution of an aliphatic sulfonic acid containing 8 to 24 carbon atoms. Branched chain aliphatic sulfonic acids are more effective than the linear aliphatic sulfonic acids, and branching at the carbon bearing the sulfonic acid group is more effective than branching at any other carbon. Contacting the fiber with the solution of the aliphatic sulfonic acid needs to be done under acidic conditions, most preferably at a pH between 0.5 to 5.0.

    Abstract: There are described vinyl ether terminated ester oligomers which cure or polymerize particularly rapidly, especially by cationic polymerization which is radiation induced in the presence of an onium salt. The oligomeric units arise most often from the reaction of a dicarboxylic acid with a diol, although esters with triols and higher polyhydric polyols also are useful, especially where an extensively cross-linked product is desired. The carboxyl-terminated oligomeric esters are esterified with vinyl ether terminated alcohols which can be thought of as the adducts of alkynes and polyols, especially diols.
