ABSTRACT:
This invention relates to normally solid linear polyester waxes which contain from about 5 to about 50 mol percent of a mixture of aliphatic dibasic acids which are chemically combined in the polyester molecule. The polyester waxes may be substantially amorphous solids or low-melting solids with melting points up to about 200.degree. C. and a heat of fusion of less than 7 cal/g. These polyester waxes are useful in preparing coating compositions for extrusion coating of paper, paperboard, or metal foils such as aluminum foil or in the lamination of these substrates.
