摘要： This invention pertains to improved polyester polyol compositions comprising 1,3-cyclohexanedimethanol (1,3-CHDM). Coating compositions based on such polyester polyols are capable of providing a good balance of the desirable coating properties, such as solvent resistance, acid resistance, retort resistance, microcracking resistance, and bending ability, for metal packaging applications.

摘要： Resin particles include resin base particles and silica particles on surfaces of the resin base particles. The silica particles contain a quaternary ammonium salt and have hydrophobized surfaces. A difference (detection temperature A−detection temperature B) between a detection temperature A and a detection temperature B is more than 50° C., where the detection temperature A is a detection temperature from a pyrolysis product of the quaternary ammonium salt determined by pyrolysis mass spectrometry of the resin particles before cleaning, and the detection temperature B is a detection temperature from the pyrolysis product of the quaternary ammonium salt determined by pyrolysis mass spectrometry of the resin particles after cleaning.

摘要： In various examples, methods of forming a polymer (e.g., a condensation polymer including but not limited to a polyester), include the steps of forming a mixture comprising one or more monomer(s), one or more biocatalyst(s), and carbon dioxide. In various examples, the methods are at least partially carried out in sub critical carbon dioxide or supercritical carbon dioxide. In various examples, a polymer is a condensation polymer. In various examples, a fabricated article, which may be a medical article, includes one or more polymer(s).

摘要： The present invention relates to a functional resin composition comprising a biomass-derived component, and more particularly to a functional resin composition comprising: a biomass-derived component; an aromatic dicarboxylic acid; an alcohol component; a chain extender; and a multifunctional compound. The biomass-derived component is biomass-derived succinic acid alone or a mixture of biomass-derived succinic acid alone and fossil-derived aliphatic dicarboxylic acid. The functional resin composition comprising these components has excellent processability, moldability, tearing strength and tensile strength, and does not easily change over time due to its excellent hydrolysis resistance.

摘要： This invention pertains to polyester compositions and their use in low shear manufacturing processes. More particularly, this invention pertains to polyester compositions that have a sharp transition from solid to flowable melt, a steep viscosity curve with temperature resulting in minimal heating above the melting temperature for good flow and having minimal cooling requirements. The polyesters have particular utility in low shear polymer melt processes such as rotational molding, powder slush molding, powder coating and 3D printing processes. The polyesters are comprised of at least one dicarboxylic acid, at least one dihydroxy alcohol, at least one polyol, and optionally a multi-functionalized acid, alcohol or anhydride branching agent. The polyesters have a puddling curve slope of −2 to −20.
