Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
201 words
A foamable composition having an acid pH comprising a resin or latex formulation and a mixture for foaming said resin or latex formulation which comprises a foamable mixture of: (a) 2 to 20 parts of a highly ethoxylated alkylphenol of the formula: ##STR3## wherein R is a saturated or unsaturated, linear or branched alkyl having from 7 to 20 carbon atoms and x has an average value of from 20 to 200; (b) 2 to 20 parts of an alkali metal N-alkyl sulfosuccinamate of the formula: ##STR4## wherein R' is a saturated or unsaturated, linear or branched alkyl having from 16 to 24 carbon atoms and M is hydrogen or an alkali metal atom with the proviso that at least one M group is an alkali metal atom; and (c) 3 to 40 parts of an alkali metal alkyl sulfate of the formula: R"OSO.sub.3 M' wherein R" is a saturated or unsaturated, linear or branched alkyl having from 7 to 24 carbon atoms and M' is an alkali metal atom; wherein said parts of components (a), (b) and (c) are parts per 100 parts by weight of dry resin (phr) present in said resin or latex formulation in said foamable composition.
Claim 2
Dependent Claim
201 words
A foamable composition having an acid pH comprising a resin or latex formulation and a mixture for foaming said resin or latex formulation which comprises a foamable mixture of: (a) 2 to 20 parts of a highly ethoxylated alkylphenol of the formula: ##STR3## wherein R is a saturated or unsaturated, linear or branched alkyl having from 7 to 20 carbon atoms and x has an average value of from 20 to 200; (b) 2 to 20 parts of an alkali metal N-alkyl sulfosuccinamate of the formula: ##STR4## wherein R' is a saturated or unsaturated, linear or branched alkyl having from 16 to 24 carbon atoms and M is hydrogen or an alkali metal atom with the proviso that at least one M group is an alkali metal atom; and (c) 3 to 40 parts of an alkali metal alkyl sulfate of the formula: R"OSO.sub.3 M' wherein R" is a saturated or unsaturated, linear or branched alkyl having from 7 to 24 carbon atoms and M' is an alkali metal atom; wherein said parts of components (a), (b) and (c) are parts per 100 parts by weight of dry resin (phr) present in said resin or latex formulation in said foamable composition.
