Abstract
Abstract Emulsifiable polyolefin waxes are prepared by reacting low molecular weight homo- and copolymers containing at least one alphaolefin monomer having at least three carbon atoms with crotonic acid in the presence of a free radical source. These emulsifiable polyolefin waxes form excellent nonionic emulsions which are useful as low color floor polishes.
