Abstract: A resin powder material comprising copolymerized polybutylene terephthalate resin powder and an inorganic substance, for example, fumed silica, having an average primary particle diameter of 100 nm or less in an amount up to 1.0 wt %. The polybutylene terephthalate resin comprises from 5 mol % to 15 mol % of Isophthalic acid and has powder with average particles diameter of 79 ?m and a maximum particles diameter of 106 ?m. Powder is obtained by grinding pellets of the copolymerized polybutylene terephthalate resin having a viscosity of 0.85 to 1.0 dl/g. Powder composition used for production of molded articles by powder laminate molding process.
Abstract: Compositions and methods for a semicrystalline poly(aryl ether ketone) copolymers incorporating 2-benzimidazolinone and 4,4?-biphenol as comonomer units with 4,4?-dihalobenzophenone, and compositions and methods for semicrystalline poly(aryl ether ketone) copolymers incorporating 2-benzimidazolinone and 4,4?-biphenol as comonomer units with 1,4-bis(4-dihalobenzoyl)benzene are described herein. The Copolymers have advantageous properties, particularly in terms of high glass transition temperatures (Tg), high melting temperatures (Tm), crystallinity and chemical resistance. The copolymers are suitable for manufacturing high temperature and chemical resistance molded systems and other articles of manufacture via injection molding, extrusion, compression molding, coating, and additive manufacturing.
Abstract: A method of preparing a graft copolymer includes a step of performing coagulation by adding an acid coagulant to 100 parts by weight (based on solids) of graft copolymer latex prepared by graft-polymerizing an aromatic vinyl compound and a vinyl cyanide compound onto conjugated diene rubber latex; and a step of performing coagulation once more by adding a salt coagulant thereto. In a resulting graft copolymer, coagulation efficiency may be improved and the gloss of the prepared graft copolymer may be increased. In addition, since a b-value measured using a Hunter lab colorimeter and a b-value measured after being left at 250° C. for 15 minutes are low, the graft copolymer may have excellent color characteristics. In addition, since heating loss is low and scorch time is long, the graft copolymer may have excellent processing characteristics.
