    摘要： 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.

    摘要： Disclosed are apparatuses and methods including incorporation of additives into a bulk materials container by coating, impregnating, or otherwise applying the additives to at least a portion of the container and/or the material comprising the container. The container may be intended for containing bulk material used in a batch or continuous process, where the container can be consumed by the process along with the bulk material. The additives incorporated into the container can be substances that may be used by the process. The additives can modify the process. The additives can modify and/or condition the product being formed by the process.

    摘要： The disclosure relates to a light color or a low color rosin or a rosin ester composition. The rosin ester comprises a reaction product of one or more rosins, one or more polyhydric alcohols, and optionally one or more monocarboxylic acids, and optionally one or more polycarboxylic acids having from 2 to 54 carbon atoms; from 0 ppm to 200 ppm of a co-catalyst, and optionally, a disproportionation catalyst, an esterification catalyst, or combinations thereof. The co-catalyst has a triplet formation quantum yield (ϕT) of greater than 0.5 and a triplet lifetime (τT) of greater than 0.5 microseconds. Methods to prepare the rosin ester compositions and uses of the compositions are also disclosed.

    摘要： A pressure-sensitive adhesive transfer tape that may have on one surface of a release substrate made of paper or a plastic film, a pressure-sensitive transfer layer having an adhesion inhibiting layer and an adhesive layer, wherein the adhesion inhibiting layer and the adhesive layer are successively stacked on one another. The adhesion inhibiting layer may prevent the adhesive layer formed on one adherend from being in contact with another adherend to weaken the adhesion between the one and another adherends, enabling the one and another adherends to be easily separated from each other. With the passage of time after being put on one another, the adhesion inhibiting layer may migrate to another adherend, so that the adherend is in contact with the adhesive layer, exhibiting strong adhesion properties between the adherends.

    摘要： A light color or a low color rosin or a rosin ester composition is disclosed. Significant color improvement can be obtained for a low color rosin, or a rosin ester by using a co-catalyst. In one embodiment, the co-catalyst has a triplet formation quantum yield (ϕT) of greater than 0.5 and a triplet lifetime (τT) of greater than 0.5 microseconds In another embodiment, the co-catalyst is selected from acridone, anthrone, 9-fluorenone, thioxanthone, xanthone, derivatives and combinations thereof.

    摘要： An oligoester composition which is a reaction product of a reactant mixture comprising one or more rosins; at least 15% by weight of one or more monocarboxylic acids; and one or more polyhydric alcohols. A method for preparing an oligoester composition comprising (a) esterifying a mixture comprising one or more rosins, one or more monocarboxylic acids, and optionally one or more polycarboxylic acids with one or more polyhydric alcohols to form the oligoester composition. An oligoester composition which is an esterification reaction product of one or more rosins, one or more monocarboxylic acids, one or more polyhydric alcohols, and optionally one or more polycarboxylic acids, wherein the composition has a weight average molecular weight of from 500 g/mol to 8,000 g/mol and a Tg of between −80° C. and 100° C.
