Abstract: There is provided a method for efficiently produce hydroxypropyl methyl cellulose acetate succinate (HPMCAS) having excellent flowability, where acetic acid in a reaction product mixture subjected to a wash and recovery step can be reduced. More specifically, there is provided a method for producing HPMCAS including an esterification step of esterifying hydroxypropyl methyl cellulose (HPMC) with acetic anhydride and succinic anhydride in acetic acid as a solvent to obtain a reaction product solution containing HPMCAS; a water addition step of adding water to the reaction product solution to obtain a water-added reaction product solution; an acetic acid removal step of removing at least a portion of both the solvent acetic acid and acetic acid derived from the acetic anhydride from the water-added reaction product solution to obtain a mixture having an acetic acid content reduced; and a wash and recovery step of washing the mixture and recovering the HPMCAS.

Abstract: Rheology-modified, additive-containing ethylenic polymer compositions are prepared in a continuously operated extruder comprising first, second and third zones by a process comprising the steps of:



mixing in the second zone of the extruder an ethylenic polymer and a high-temperature decomposing peroxide at a temperature such that the half-life of the peroxide is equal to or greater than (≥) one minute and for a sufficient period of time to modify the rheology of the ethylenic polymer to produce a rheology-modified, melted ethylenic polymer for transfer to the third zone of the extruder; and
adding to the third zone one or more additives to the rheology-modified, melted ethylenic polymer to produce the rheology-modified, additive-containing ethylenic polymer.

Abstract: A method for directly preparing a foamed polylactic acid (PLA) product from a PLA melt includes PLA melt preparation, feeding, and two-stage extrusion. In the two-stage extrusion, a pressure at an outlet of a first-stage twin-screw extruder is 15 MPa to 17 MPa, a PLA melt is fed at a rate of 250 kg/h, a foaming additive is fed at a rate of 7.5 kg/h to 10 kg/h, and a foaming gas is fed at a rate of 2.8 L/h to 7.5 L/h. The method can ensure both foamability and quality of a material and reduce more than ⅓ of energy consumption; and an obtained product has an adjustable foaming rate of 3 to 25, a crystallinity of 40.3% to 48.5%, a tensile strength of 8.7 MPa to 19.6 MPa, and an apparent density of 0.05 g/cm3 to 0.4 g/cm3.

Abstract: A fluid-flow-modification plate comprises a monolithic body, having an inlet-side surface, an outlet-side surface, a first passage, a second passage, a third passage, and a fourth passage. The first passage, second passage, third passage, and fourth passage each extend between the inlet-side surface and the outlet-side surface. The first passage and second passage intersect each other at a first intersection boundary. The third passage and fourth passage intersect each other at a second intersection boundary. The first passage and third passage do not intersect each other. The first passage and fourth passage do not intersect each other. The second passage and third passage do not intersect each other. The second passage and fourth passage do not intersect each other. The first-passage-inlet-opening perimeter boundary has single-point contact with the fourth-passage-inlet-opening perimeter boundary. The second-passage-outlet-opening perimeter boundary has single-point contact with the third-passage-outlet-opening perimeter boundary.
