Abstract
Abstract Process for the preparation of esterified or metal-containing polyolefin waxes which comprises esterifying or neutralizing maleinated polyolefins with a polyhydric alcohol or with a metal compound in which the metal is selected from those of Group II of the Periodic Table; and aqueous polishing emulsions containing as the main ingredient the esterified or metal-containing polyolefin wax. This invention also relates to aqueous polishing emulsions containing the maleinated polyolefin wax as the main ingredient.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
In a process for preparing a metal-containing polyolefin wax comprising melting a reaction product of a starting polyolefin wax having an average molecular weight of 400 - 1,500 and an ethylenically unsaturated dibasic acid having 4 - 5 carbon atoms or anhydride thereof and reacting the melted reaction product with a metal compound in which the metal is selected from the metals of Group II of the Periodic Table, to produce an acid-modified polyolefin wax, the improvement which comprises reacting said acid-modified polyolefin wax and Group II metal compound at 100°-200° C in the presence of water or a volatile acid as a catalyst thereby to obtain the metal-containing polyolefin wax.
Claim 2
Dependent Claim
111 words
