Publication number: 20170107324Abstract: The invention relates to a method of isolation of polyhydroxyalkanoates from biomass fermented by microorganisms producing polyhydroxyalkanoates and/or from biomass containing at least one crop-plant producing polyhydroxyalkanoates in which from the biomass which, if fermented, is first inspissated by the isolation from a fermentation medium to a dry matter content of at least 20%, polyhydroxyalkanoates are extracted with an extraction agent based on chlorinated hydrocarbon, whereupon from the extraction solution thus obtained an extract is separated, from which the extraction agent is removed and polyhydroxyalkanoates precipitate. Prior to the extraction of polyhydroxyalkanoates, components of the biomass other than polyhydroxyalkanoates are extracted from the biomass by means of an extraction agent based on alkyl alcohol having 2 to 4 carbon atoms in the chain, which is added to the biomass in a weight ratio of 1:0.Type: ApplicationFiled: June 2, 2015Publication date: April 20, 2017Applicant: NAFIGATE CorporationInventors: Jiri Trejbal, Martin Zapletal

Publication number: 20170107326Abstract: The invention relates to copolyamides which are formed from a diamine component, a dicarboxylic acid component and possibly a lactam- and/or ?-amino acid component. Furthermore, the invention relates to a polyamide moulding compound which comprises at least one of these copolyamides. Moulded articles produced from these moulding compounds are used in the automobile field, in the domestic field, in measuring-, regulating- and control technology or in mechanical engineering.Type: ApplicationFiled: October 5, 2016Publication date: April 20, 2017Applicant: EMS-PATENT AGInventors: Andreas BAYER, Manfred HEWEL

Publication number: 20170107327Abstract: Hydroxypolyamides, hydroxypolyamide products, and post-hydroxypolyamides are disclosed as gel forming agents. Hydroxypolyamides and post-hydroxypolyamides are prepared from known methods. Hydroxypolyamide products are produced from a modified polymerization procedure which utilizes strong base for deprotonation of ammonium salts from the esterification of stoichiometrically equivalent polyacid:polyamine salts. The hydroxypolyamide products are capable of gel formation at lower concentrations than hydroxypolyamides and post-hydroxypolyamides from the known methods of preparation, and are therefore superior gel forming agents.Type: ApplicationFiled: October 26, 2016Publication date: April 20, 2017Inventors: Donald E. Kiely, Tyler N. Smith
