| 20090318589 | Additive composition for mortars, cements and joint compounds and cementitious compositions made therefrom - An additive composition for mortars, exterior insulation finish systems, self-leveling compounds and joint compounds is disclosed. The additive composition contains a nitrogen-containing polymer and a reactive agent capable of forming a crosslinking reaction with the nitrogen-containing polymer. Small amounts of the additive composition contained in a product cannot only increase one or more properties of the product but can also minimize the use of redispersible polymers in the product. | 12-24-2009 |
| 20110159308 | IMPROVED BARRIER LAYER - Disclosed herein is a barrier layer comprising a polyvinyl amine-polyvinyl alcohol copolymer applied to a substrate as a water-soluble composition, wherein the polyvinyl amine-polyvinyl alcohol copolymer is formed by copolymerizing: (a) from 99 to 1 mol % of N-vinylformamide and (b) from 1 to 99 mol % of one or more vinyl Ci-Ci0 alkyl esters, and then hydrolyzing from 30 to 100 mol % of the formyl groups from the copolymerized units (a) to form amino groups and from 30 to 100 mol % of the Cj-Cio alkyl ester groups from the copolymerized units (b) to form hydroxyl groups, wherein the copolymer has a unimodal compositional distribution as evidenced by essentially one peak in a gel permeation gradient elution chromatographic analysis. A method of producing a barrier layer is also disclosed. | 06-30-2011 |
