Abstract
This invention relates to the emulsifiable polyolefin waxes which are prepared by reacting pivalolactone with a polyolefin wax containing carboxyl groups and the process for their preparation whereby the carboxyl groups are converted into carboxylate anions and grafted with pivalolactone to prepare emulsifiable waxes having improved properties. Polyolefin waxes which contain carboxyl groups include oxidized high, medium and low density polyethylene waxes, oxidized ethylene/alpha-olefin waxes, ethylene-acrylic acid copolymer waxes, ethylene-methacrylic acid copolymer waxes and high, medium and low density polyethylene, polypropylene and ethylene/alpha-olefin copolymer waxes which have been grafted or reacted with an unsaturated polycarboxylic component.
