发明人：WOSNICK JORDAN H
权利人:XEROX CORP
摘要:The present disclosure provides for enzymatic polymerization to produce polyester resins suitable for use in manufacturing toners. In embodiments, crystalline copolymers, which are polyesters, may be synthesized from lactones, cyclic anhydrides, cyclic carbonates, and combinations thereof. These crystalline copolymers, in turn, may be utilized in the synthesis of toner particles.

标题:Preparation of azo pigments with low pcb content by coupling in the presence of olefins
发明人：RIEPER WOLFGANG
权利人:HOECHST AG
摘要:The production which is customary in practice of monoazo compounds based on dichloro- and trichloroanilines or disazo compounds of the chlorinated biphenyl series by conventional coupling methods meets with difficulties in that the resulting pigments are contaminated by traces of polychlorinated biphenyls. n According to the invention, it has now been found that by addition of water-soluble olefins of the type ##STR1## (R =H, alk or Oalk; X =--COOR 1 , --CONHR 2 or --NR 3 COR 4 ) n in the azo coupling, the side reactions which form PCBs can be decidedly suppressed during synthesis of the pigments.

权利人:HOECHST AG
摘要:Free radical heavy metal ions in water-soluble heavy metal complex dyestuffs are removed from the synthesis solution of the heavy metal complex dyestuff by means of a compound or several of the compounds mentioned below: (a) saturated and unsaturated fatty acids having about 8 to 18 carbon atoms and water-soluble salts thereof; (b) the monoesters and diesters of orthophosphoric acid and salts thereof corresponding to the general formula (1a) and (1b) in which R denotes a saturated or unsaturated aliphatic radical having about 8 to 18 carbon atoms and M stands for a hydrogen atom or a salt-forming, water-solubilizing metal; (c) aliphatic sulfonic acids and water-soluble salts thereof corresponding to the general formula (2) R-SO3M (2) in which R and M have the abovementioned meanings; (d) aliphatic phosphonic acids and monoesters thereof and also water-soluble salts thereof corresponding to the general formulae (3a) and (3b) in which R and M have the abovementioned meanings; (e) malonic acid and water-soluble salts thereof; (f) trimercapto-s-triazine, 2-aminobenzoic acid, 8-hydroxyquinoline and water-soluble salts of these compounds; (g) water-soluble sulfides, in particular alkali metal sulfides; (h) functionalized water-insoluble polymers which react with metal ions by the ion-exchanger principle or form metal chelate complexes. Using these compounds, the excess heavy metal ions are precipitated out of the synthesis solution or separated off, without the heavy metal ions bound as a complex in the dye being attached.
