权利人:BASF SE
摘要:An apparatus for synthesis of a polymer with separation of a gaseous substance comprises a reaction space having an essentially circular cylindrical upper section which is bounded by two circular faces and one shell face and has a longitudinal cylinder axis, and a lower section, an inlet orifice disposed in a circular face or the shell face of the upper section, a first outlet orifice disposed in a wall of the lower section, a second outlet orifice disposed in the shell face of the upper section opposite the first outlet orifice, and a removal device which is disposed so as to be rotatable about the longitudinal cylinder axis and is in contact with both circular faces and the shell face. This apparatus can especially be used for performance of a process including the feeding of an oligomer melt into a reaction space through an inlet orifice, the polymerization of the oligomer melt to give a polymer melt, the removal of the polymer melt from the reaction space through a first outlet orifice of the reaction space, and the removal of a gaseous substance from the reaction space through a second outlet orifice of the reaction space, wherein deposits on at least one inner wall of the reaction space are removed by a removal device and transported into the oligomer melt.

标题 :Poly-phenylated diamines and their use as polycondensation monomers in the synthesis of polyamide, poly(amide-imide), and polyimide polymers
发明人：HARRIS FRANK W
权利人:UNIV AKRON
摘要:New polyphenylated polynuclear aromatic diamines, such as 1,3-bis[4-aminophenyl]-2,3,5-triphenylbenzene, a process for their manufacture and their use as polycondensation components for the manufacture of polyamide, polyamide-imide and polyimide polymers are described. The polymers obtained with the aromatic diamines according to the invention are readily soluble, rigid-rod polymers and are distinguished by outstanding modulus, tensile compression strength, energy absorption, coefficient of expansion and electrical properties.

摘要:Provided is a semi-aromatic polyamide, comprising, on the basis of the molar content of all repeating units, the following repeating units: 46‑54 mol% of 10T unit derived from 1,10‑diaminodecane and terephthalic acid, 46-54 mol% derived from one or more monomers in diacid Y containing 4-36 carbon atoms, and XY unit consisting of one or more monomers in diamine X containing 4-36 carbon atoms; the 10T unit and XY unit in the semi-aromatic polyamide chain segment are arranged in an alternating order ... 10TXY10TXY10TXY 10TXY10TXY ...; the semi-aromatic polyamide at least contains three monomers. In the semi-aromatic polyamide prepared by means of the special preparation method, 10T and XY units are arranged alternately, and in comparison with ordinary random copolymerized semi-aromatic polyamides, it has higher crystallinity and a higher melting point, and the water absorption rate is low.

标题:Polyurethane synthesis from functional group terminated polymers containing sulfonate groups
发明人：CHANG WALLY L
权利人:WITCO CORP
摘要:Disclosed is a process for producing water-dispersible polyurethanes by forming an isocyanate-di-substituted prepolymer and reacting it with a chain extender. The prepolymer can be formed by reacting a diisocyanate with an ethylenically unsaturated precursor which is preferably formed by condensation polymerization of reactants including ethylenically unsaturated reactants and then sulfonating the ethylenic unsaturation of said polymeric precursor by reacting it with a sulfonating agent such as bisulfite, metabisulfite, or a mixture thereof.
