Claims
- 1. A method of modifying a masonry composition comprising:treating the masonry composition with a polymer; wherein a composition comprising the masonry composition and the polymer consists essentially of the masonry composition, the polymer, and optionally, at least one component selected from the group consisting of fillers, inorganic pigments, organic pigments, and water; wherein the polymer comprises as polymerized units: a) from 20 to 100 parts by weight of at least one C12 to C40 alkyl ester of (meth)acrylic acid, b) from 0 to 80 parts by weight of at least one ethylenically unsaturated monomer, and c) from 0 to 80 parts by weight of at least one ethylenically unsaturated acid containing monomer or salts thereof, provided that when the at least one ethylenically unsaturated monomer is selected from the group consisting of hydroxyethyl (meth)acrylate and hydroxypropyl (meth)acrylate, the combined total level of hydroxyethyl (meth)acrylate and hydroxypropyl (meth)acrylate ranges from 0 to 40 parts; and wherein the polymer is an emulsion polymer prepared by emulsion polymerization.
- 2. The method according to claim 1 wherein the masonry is treated by admixing the polymer with the masonry.
- 3. The method according to claim 1 wherein the masonry is treated by admixing the polymer with a slurry coating for the masonry and applying the slurry coating to the masonry.
- 4. The method according to claim 1 wherein the masonry is treated by applying a coating of the polymer to the masonry.
- 5. A composition consisting essentially of:I) masonry; and II) a polymer comprising as polymerized units: a) from 20 to 100 parts by weight of at least one C12 to C40 alkyl ester of (meth)acrylic acid, b) from 0 to 80 parts by weight of at least one ethylenically unsaturated monomer, and c) from 0 to 80 parts by weight of at least one ethylenically unsaturated acid containing monomer or salts thereof, provided that when the at least one ethylenically unsaturated monomer is selected from the group consisting of hydroxyethyl (meth)acrylate and hydroxypropyl (meth)acrylate, the combined total level of hydroxyethyl (meth)acrylate and hydroxypropyl (meth)acrylate ranges from 0 to 40 parts; and III) optionally, at least one component selected from the group consisting of fillers, inorganic pigments, organic pigments, and water; wherein the polymer is an emulsion polymer prepared by emulsion polymerization.
- 6. An article consisting essentially of the composition of claim 5 wherein the masonry is concrete.
- 7. An article consisting essentially of the composition of claim 5 wherein the masonry is a concrete roof tile.
- 8. The composition according to claim 5 wherein the masonry is a slurry coated concrete roof tile.
- 9. The composition according to claim 5 wherein the masonry is a polymer coated, slurry coated concrete roof tile.
- 10. The method according to claim 1 wherein the polymer comprises as polymerized units 30 to 100 parts by weight of at least one C12 to C40 alkyl ester of (meth)acrylic acid.
- 11. The method according to claim 1 wherein the polymer is prepared in the presence of methyl-β-cyclodextrin.
- 12. The composition of claim 5 wherein the polymer comprises as polymerized units 30 to 100 parts by weight of at least one C12 to C40 alkyl ester of (meth)acrylic acid.
- 13. The composition of claim 5 wherein the polymer is prepared in the presence of methyl-β-cyclodextrin.
