摘要： The present invention relates to a composition comprising an aqueous dispersion of multiphase polymer particles comprising first polymer particles having a Tg of less than 30° C. and second polymer particles having a Tg in the range of from 100° C. to 110° C., wherein the second polymer particles are phase separated from and occluded within the first polymer particles; wherein the number average molecular weight (Mn) of the multiphase polymer particles is in the range of from 9,000 to 25,000 g/mole; and wherein the second polymer particles comprise at least 95 weight percent methyl methacrylate. The composition of the present invention is useful in a formulation that can be used to prepare a water-resistant blister free LASD coating with little or no surface defects.

摘要： Polyesters, such as those formed using polyols and di- or tri-carboxylic acids or anhydrides or salts thereof, are used as foam control agents in foodstuff processing. The polyesters are biodegradable and biocompatible while still providing excellent foam control capacity. In addition, polyesters foam control agents of the disclosure can be used with various apparatus while avoiding forming films that otherwise affect apparatus function. The polyesters can be used at various stages during industrial processing of vegetables (e.g., potatoes and beets) and fruits.

摘要： The present invention relates to opaque polymers functionalized with phosphorus acid groups, composites of TiO2 particles and the opaque polymers, and methods for their preparation. The composites are useful in coatings formulations and have been shown to exhibit improved hiding benefits in coated substrates over compositions containing non-functionalized opaque polymer and TiO2.
