Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
17 words
A normally liquid, substantially fully mixed-alkylated, substantially fully methylolated glycoluril derivative consisting essentially of dimethoxymethyl diethoxymethyl glycoluril.
Claim 2
Dependent Claim
17 words
A normally liquid, substantially fully mixed-alkylated, substantially fully methylolated glycoluril derivative consisting essentially of dimethoxymethyl diethoxymethyl glycoluril.
Claim 3
Dependent Claim
172 words
A composition of matter comprising a blend of from about 2% to about 50% by weight of a normally liquid, substantially fully mixed-alkylated, substantially fully methylolated glycoluril derivative which is essentially dimethoxymethyl diethoxymethyl glycoluril and correspondingly between about 98% and 50%, by weight of a non-gelled, polymeric material carrying an anionic charge, said polymeric material containing at least one class of reactive groups selected from the group consisting of carboxyl groups, alcoholic hydroxyl groups and amide groups, the amount of said groups in said polymeric material being at least about 0.5%, by weight, and not more than about 20%, by weight, based on the total weight of said polymeric material; said groups being reactive with said glycoluril derivative and said percentages of said glycoluril derivative and said polymeric material being based on the total weight of said glycoluril derivative and said polymeric material, said composition also containing from about 0.5% to about 5.0%, by weight, based on the total weight of said glycoluril derivative and said polymeric material, of an acid catalyst.
Claim 4
Dependent Claim
172 words
A composition of matter comprising a blend of from about 2% to about 50% by weight of a normally liquid, substantially fully mixed-alkylated, substantially fully methylolated glycoluril derivative which is essentially dimethoxymethyl diethoxymethyl glycoluril and correspondingly between about 98% and 50%, by weight of a non-gelled, polymeric material carrying an anionic charge, said polymeric material containing at least one class of reactive groups selected from the group consisting of carboxyl groups, alcoholic hydroxyl groups and amide groups, the amount of said groups in said polymeric material being at least about 0.5%, by weight, and not more than about 20%, by weight, based on the total weight of said polymeric material; said groups being reactive with said glycoluril derivative and said percentages of said glycoluril derivative and said polymeric material being based on the total weight of said glycoluril derivative and said polymeric material, said composition also containing from about 0.5% to about 5.0%, by weight, based on the total weight of said glycoluril derivative and said polymeric material, of an acid catalyst.
Claim 5
Dependent Claim
14 words
A composition according to claim 2 wherein said acid catalyst is p-toluene sulfonic acid.
