Abstract
Polymer compositions which are useful to improve water repellency and durability in fiber, nonwoven, textile, and paper compositions are disclosed. A method of improving water repellency and durability in fiber, nonwoven, textile, and paper compositions is also disclosed.
Claims2
A composition comprising:
- i) an emulsion polymer comprising as polymerized units:
- a) from 40 to 99 parts by weight of at least one C12 to C40 alkyl ester of (meth)acrylic acid,
- b) from 0 to 50 parts by weight of at least one monomer selected from the group consisting of methyl methacrylate and butyl acrylate;
- c) from 0 to 50 parts by weight methacrylic acid;
- and
- d) from 0.1 to 5 parts by weight of at least one cross-linking monomer selected from the group consisting of (meth)acrylamide, n-methylol (meth)acrylamide, and mixtures thereof,
- wherein the emulsion polymer is prepared by emulsion polymerization;
- and
- ii) from 0 to 10 parts by weight, based on the polymer weight of at least one cross-linking agent,
- provided that the composition contains 0.1 to 10 parts by weight, based on the polymer weight cross-linking monomer and cross-linking agent.
