ABSTRACT:
Novel rubber latex compounds comprise an aqueous dispersion of a natural or synthetic rubber latex and as a foaming agent an alkyl alkoxy sulphosuccinamate of the formula: ##STR1## wherein R represents an alkyl group having from 7 to 18 carbon atoms, one of X and Y represents a hydrogen atom and the other represents a SO.sub.3 group, n is an integer having a value of from 0 to 5 and R.sub.1 represents an alkylene group comprising 2 or 3 carbon atoms. These foaming agents combine the virtues of acceptable foaming properties with relatively high solubility in aqueous solution. They can be prepared and transported as aqueous concentrates containing up to 45% of solids material.
Those compounds wherein R.sub.1 represents a branched chain alkyl group are believed to be novel and are claimed as such.
