  • Patent number: 11634584
    Abstract: Disclosed are compositions which include an ethylene polymer derived from at least one polar monomer with one or more ester groups, and a rosin ester. The rosin ester can have a low hydroxyl number (e.g., a hydroxyl number seven or less), a low acid number (e.g., an acid number of ten or less), a relatively low PAN number (e.g., a PAN number less than twenty-five), a relatively high third moment or third power average molecular weight (Mz), (e.g., an Mz value in between 2500 and 12000 g/mol), a low sulfur content (e.g., a sulfur content lower than 600 ppm prior to antioxidant addition) or combinations thereof. The compositions can exhibit a high heat stress resistance (e.g., a heat stress pass temperature value higher than 52° C. or in between 48° C. and 60° C.) and/or improved viscosity stability and/or color stability upon thermal aging and/or improved compatibility.

  • Publication number: 20180223136
    Abstract: Disclosed are compositions which include an ethylene polymer derived from at least one polar monomer with one or more ester groups, which polymerize with ethylene, (e.g., a copolymer derived from ethylene and vinyl acetate or a copolymer derived from ethylene and n-butyl acrylate) and a rosin ester. The rosin ester can have a low hydroxyl number (e.g., a hydroxyl number six or five or less), a low acid number (e.g., an acid number of ten or less), a low PAN number (e.g., a PAN number of eight or less), or combinations thereof. The compositions can exhibit improved viscosity stability and/or color stability and/or a decreased amount of char particle formation upon thermal aging.

  • Publication number: 20180086942
    Abstract: Novel oligoester compositions having desirable user and/or process-desired combination of properties. The oligoester compositions are derived from one or more rosin; one or more polyhydric alcohol; and one or more polyfunctional carboxylic acid. The carboxylic acids have 5 to 19 carbon atoms. The one or more polyfunctional carboxylic acids may be polyfunctional carboxylic acids and aliphatic dicarboxylic acids. In some embodiments, the novel oligoester compositions are suitable for use in adhesives, road markings, and automotive industry, for example. Also disclosed herein are methods of producing the novel oligoester compositions.
