ABSTRACT:
A polymer comprising styrene or substituted-styrene and carboxylated monomer is prepared by a solution polymerization process, comprising first a polymerization step, followed by a neutralization step, and then a distillation step. The polymers have relatively low molecular weights, generally below about 10,000, and can have higher styrene content than has hither been possible. The polymers are found to have good soil release properties and so to be particularly useful in cleaning compositions for fabric or hard surface cleaning.
