The present disclosure is directed to polymer blends comprising a biopolymer and a substituted or unsubstituted aliphatic polyester. The aliphatic polyester comprises repeating units derivable from a substituted or unsubstituted aliphatic diacid, repeating units derivable from a substituted or unsubstituted aliphatic diol, and one or two terminator units derivable from a substituted or unsubstituted aliphatic alcohol. The polymer blends disclosed herein provide improved flexibility, and are useful, for example, in the production of packaging materials, industrial products, durable goods, and the like.

Biopolymer compositions having improved flexibility

The invention is directed to joint assemblies comprising at least two adjacent panels and a jointing composition adhering to and positioned between the at least two adjacent panels, methods for installing joint assemblies, and jointing compositions. The jointing compositions include a sealant composition and a long chain ester in an amount of about 0.1% to about 15% by weight, based on the weight of the sealant composition in the jointing composition.

Joint assemblies, methods for installing joint assemblies, and jointing compositions

A plasticized thermoplastic composition including a thermoplastic, and plasticizer compound selected from the group consisting of a cyclic dimerate ester, a cyclic trimerate ester plasticizer, and mixtures thereof.

Low polarity dimerate and trimerate esters as plasticizers for thermoplastic compositions

A thermoplastic polymer/elastomer composite composition including one or more thermoplastic polymers, a natural or synthetic rubber, and a long chain cyclic dimerate ester and/or long chain cyclic trimerate ester plasticizer.

Low polarity dimerate and trimerate esters as plasticizers for thermoplastic polymer/elastomer composites

A sealant composition comprising a sealant, an adhesive resin, and a long chain ester, particularly dimerate and trimerate esters, is capable of unexpected adhesion to substrates such as ceramic substrates (e.g., concrete), glass substrates, metal substrates such as metal flat stock materials, polymeric substrates including substrates comprising natural and/or synthetic rubbers and substrates comprising thermoplastic polymeric materials, particularly for use in sealing around bathroom fixtures, in storage areas, vents, plumbing lines, flooring, wheel wells, and the like.

Adhesion promoters for sealants

A rubber composition including a natural or synthetic rubber, and an adhesive resin capable of unexpected adhesion to metal, polymer and glass substrates, particularly cords in radical tires, hoses, conveyor belts, transmission belts, and the like by the addition of a liquid composition containing long chain esters, including mono, di- and tri-esters, and one or more reactive diluents. In the preferred embodiment, the reactive diluent is selected from (1) glycidyl ethers, (2) diglycidyl ethers; (3) aliphatic, straight chain epoxides; (4) epoxidized vegetable oils, particularly epoxidized soybean oil; (5) cycloaliphatic epoxies; (6) glycidyl esters, and (7) diglycidyl esters.

Vulcanized rubber composition with a liquid adhesion promoter containing an adhesive resin and ester

A thermoplastic polymeric material composition including a thermoplastic polymeric material selected from the group consisting of a thermoplastic polymer and a thermoplastic polymer alloy, an adhesive resin, and a long chain ester, particularly dimerate and trimerate esters, is capable of unexpected adhesion to substrates such as natural fabric substrates, synthetic polymeric fabric substrates, metal substrates, and thermoplastic polymeric material substrates, particularly natural cords, synthetic polymeric cords, metal cords, and glass cords for use in cord-reinforced articles such as hoses, conveyor belts, transmission belts, and the like.

Adhesion promoters for cord-reinforced thermoplastic polymeric materials and substrate/thermoplastic polymeric material composites

An elastomeric composition including a natural or synthetic rubber, and a cyclic dimerate ester and/or a cyclic trimerate ester plasticizer.

Low polarity dimerate and trimerate esters as plasticizers for elastomers

A rubber composition including a natural or synthetic rubber, and an adhesive resin capable of unexpected adhesion to metal, polymer and glass substrates, particularly cords in radical tires, hoses, conveyor belts, transmission belts, and the like by the addition of long chain esters, including mono, di- and tri-esters.

Adhesion promoter for cord-reinforced rubber and metal or polymer substrate/rubber composites

A rubber composition including a natural or synthetic rubber, and an adhesive resin capable of unexpected adhesion to metal, polymer and glass substrates, particularly cords in radical tires, hoses, conveyor belts, transmission belts, and the like by the addition of a liquid composition containing long chain esters, including mono, di- and trimesters.

Liquid adhesion promoter for cord-reinforced rubber and metal or polymer substrate/rubber composites

A plasticized polyvinyl chloride (PVC) resin composition and method of plasticizing and decreasing the hydrophobicity of said PVC resin for adherence of aqueous coating compositions, such as water-based inks, by incorporating into the PVC resin a polymeric plasticizer for PVC, a monomeric diacid plasticizer, comprising primarily a C.sub.5, C.sub.4 or C.sub.3 diacid plasticizer, or mixtures, in a ratio of polymeric/monomeric plasticizers of 5/95 to 95/5, preferably 90/10 to 60/40, and at least about 0.1%, based on the weight of the PVC resin, of a metal salt additive, wherein the metal salt is an oxide or a hydroxide and has an oxidation state of plus two, three or four, preferably calcium oxide and/or calcium hydroxide. The monomeric/polymeric plasticizer combination together with the metal salt additive(s) unexpectedly decreases the hydrophobicity of the PVC surface for strong adherence of water-based inks and coatings thereto.
