Abstract
A process is provided for the production of an emulsifiable polypropylene wax having a melt viscosity from 1000 to 5000 cP at 190.degree. C. This process entails reacting at a temperature below 190.degree. C. a thermally degraded polypropylene wax having a melt viscosity below 1000 cP (at 190.degree. C.) with maleic anhydride in the presence of a free radical source. Floor polish formulations containing this polypropylene wax are very clear but yet provide floor finishes that are very tough.
