Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
In a dry mortar-forming composition which comprises, by weight, from about 24% to about 99% of hydraulic cement, from about 0% to 75% sand and from about 0.3 to about 4% of a water-retaining thickener, said dry composition being capable, when mixed with from about 25% to about 40% of its own weight in water, of producing a mortar which can be applied in thin layers for setting tile on walls and ceilings, the improvement wherein the water-retaining thickener is at least one modified hydroxyethyl cellulose having hydroxethyl M.S. from about 0.3 to about 4. 0 and hydroxypropyl M.S. greater than 0.35.
Claim 2
Dependent Claim
102 words
In a dry mortar-forming composition which comprises, by weight, from about 24% to about 99% of hydraulic cement, from about 0% to 75% sand and from about 0.3 to about 4% of a water-retaining thickener, said dry composition being capable, when mixed with from about 25% to about 40% of its own weight in water, of producing a mortar which can be applied in thin layers for setting tile on walls and ceilings, the improvement wherein the water-retaining thickener is at least one modified hydroxyethyl cellulose having hydroxethyl M.S. from about 0.3 to about 4. 0 and hydroxypropyl M.S. greater than 0.35.
Claim 3
Dependent Claim
17 words
The composition of claim 1 wherein the modified hydroxyethyl cellulose has a hydroxypropyl M.S. greater than 0.6.
Claim 4
Dependent Claim
29 words

Claim 5
Dependent Claim
32 words

The composition of claim 2 which further comprises about 1%, based by weight on the thickener, of a polymer selected from the group consisting of polyacrylamide and anionic or cationic copolymers of acrylamide.
Claim 8
Dependent Claim
25 words
The composition of claim 2 which further comprises from about 0.05% to about 2%, based by weight on the hydraulic cement, of a polyvinyl alcohol.
