Abstract:
1. Cellulosic fibers having intrafiber cross-links formed with a phosphinate-containing telomer of acrylic acid having improved penetration and flow into the cellulosic fiber, the telomer having a glass transition temperature dried (T gd ) from about 70° C. to about 105° C., the telomer having a number average of monomer units of no greater than about 15, and having monoalkyl-substituted phosphinate groups and dialkyl-substituted phosphinate groups, wherein the telomer comprises the phosphinate-containing telomer of polyacrylic acid or the phosphinate-containing co-telomer of acrylic acid, the phosphinate-containing co-telomer having at least 90 wt % acrylic acid as the reactive monomer, in copolymerized form, wherein in the co-telomer, at least one co-monomer, in copolymerized form, is selected from hydroxyethyl acrylate, hydroxyethyl methacrylate, acrylamide, methacrylamide, 3-allyloxy-1,2-propane-diol, trimethylolpropaneallylether and dimethylaminoethyl(meth)acrylate, and, further, wherein the telomer has a Penetration Factor of at least 65 wt. %.
