This invention relates to new linear polyester waxes which contain as the acid member at least about 75 mol percent 1,12-dodecanedioic acid. The polyester waxes may be viscous liquids, amorphous or semicrystalline solids with melting points less than about 100.degree. C. These polyester waxes are useful as modifiers for ethylene/vinyl acetate copolymer based adhesives and as additives to improve the hardness of polyolefin coatings.

Polyester waxes based on 1,12-dodecanedioic acid

This invention relates to new emulsifiable polyester waxes which are linear polyester waxes which are end capped with polyfunctional organic anhydrides. The emulsifiable polyester waxes are generally amorphous or semicrystalline solids with melting points less than about 100.degree. C. These polyester waxes are useful in preparing clear emulsions which can be applied to surfaces to form protective and decorative films or coatings.

This invention relates to new branched polyester waxes which contain particular amounts of tri- or tetrafunctional hydroxyl containing compounds. The branched polyester waxes may be semicrystalline or crystalline solids with melting points less than about 200.degree. C. These polyester waxes are useful as modifiers for ethylene/vinyl acetate copolymer based adhesives and as additives to improve the hardness of polyolefin coatings.

Branched polyester waxes

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.

Polyester waxes based on mixed aliphatic dibasic acids

This invention relates to new linear polyester waxes which contain as the acid member at least 75 mole percent alkylsuccinic anhydride or alkenylsuccinic anhydride. The polyester waxes may be viscous oils or amorphous or semicrystalline solids with melting points less than about 100.degree. C. These polyester waxes are useful as modifiers for ethylene/vinyl acetate copolymer based adhesives and as additives to improve the hardness of polyolefin coatings.

Polyester waxes based on alkylsuccinic anhydride or alkenylsuccinic

Copolyesters derived from aromatic, cycloaliphatic or aliphatic dibasic acid moieties; aliphatic or cycloaliphatic glycol moieties including at least 10 mole % of 1,6-hexanediol moieties; and 2 to 40 mole % of an alkyl or alkenylsuccinic anhydride moiety. The copolyesters are useful as bonding or coating compositions.

Polyester modified with alkyl- or alkenylsuccinic anhydrides

Linear copolyesters derived from at least 65 mole % of 1,4-cyclohexanedicarboxylic acid moiety of which at least 85 mole % thereof is of the trans configuration; 0 to 33 mole % of an aromatic, cycloaliphatic or aliphatic dibasic acid moiety, 2 to 35 mole % of an alkylsuccinic or alkenylsuccinic anhydride moiety and one or more aliphatic or cycloaliphatic glycol moieties. The copolyesters are useful as bonding or coating compositions.

This invention is directed to blends of polymers of 2-substituted norbornenes such as poly(2-methoxycarbonyl-5-norbornene) and plasticized poly(vinyl chloride). These blends provide plasticized poly(vinyl chloride) compositions having high clarity as well as improved low temperature flexibility and improved low temperature impact strength.

This invention relates to blends of plasticizing oils and compatible tackifiers with olefin copolymers containing propylene, either 1-butene or 1-pentene and 3 to 14 mole percent of at least one C.sub.6 to C.sub.10 linear .alpha.-olefin which are useful as hot-melt, pressure-sensitive adhesives. The unmodified copolymer base resins have melt viscosities in the range of 10,000 cp up to about 1,000,000 cp at 190.degree. C. The addition of the plasticizing oils and compatible tackifiers to the copolymer base resin causes a dramatic and unexpected increase in the shear adhesion failure time in addition to improved coatability as well as substantial increases in probe tack and peel adhesion values of the copolymers.

Blends of propylene/1-butene or 1-pentene/higher .alpha.-olefin

This invention relates to blends of compatible tackifiers with substantially amorphous olefin copolymers containing at least one C.sub.3 to C.sub.5 linear .alpha.-olefin and 40 to 60 mole percent of at least one C.sub.6 to C.sub.10 linear .alpha.-olefin which are useful as hot-melt, pressure-sensitive adhesives. The unmodified copolymer base resins have melt viscosities in the range of &gt;75,000 cp up to about 1,000,000 cp at 190.degree. C. The addition of the compatible tackifiers to the copolymer base resin causes a dramatic and unexpected increase in the shear adhesion failure time in addition to improved coatability as well as substantial increases in probe tack and peel adhesion values of the copolymers.

The hot-melt adhesives of the present invention comprise a blend of poly(propylene-co-higher 1-olefin), tackifying resin and crystalline propylene containing polymer. These hot-melt adhesive compositions have a novel combination of properties including strong T-peel and lap shear bonds to both low- and high-density polyethylene with excellent creep resistance at ambient temperatures. Therefore, these new hot-melt adhesives are excellent adhesives for applications such as sealing high-density polyethylene grocery bags and low-density shipping bags.
