154 PROCESS FOR PREPARING A POLYMER COMPOSITION, AND POLYMER COMPOSITION OBTAINABLE BY SAID PROCESS US15744263 2016-07-22 US20180201731A1 2018-07-19 Hans Klaas VAN DIJK; Michiel Gerardus Henricus Maria BALTUSSEN
The invention relates to a process for preparing a polymer composition, comprising a blending step wherein a first polymer (component A1) and at least one further component are dosed into and mixed in a mixing apparatus, and wherein the first polymer A1 is a granulate polyamide material directly obtained by direct solid state polymerization of a diammonium dicarboxylate salt prepared by fluidized bed spray granulation. The invention also relates to a dry-blend obtainable by said process.
155 METHOD AND DEVICE FOR PRODUCING POLYAMIDES, WITH OPTIMIZED FLOW MANAGEMENT US15547950 2016-02-02 US20180022870A1 2018-01-25 Bernd KÖNIGSMANN
A process for producing polyamides makes flow guidance within the process more efficient. In some respects, the process is based on the polymerization of lactam to a polyamide-containing polymer melt, the subsequent granulation of the polymer melt to polyamide granules using granulation liquid, and the subsequent extraction of monomeric and oligomeric constituents from the PA granules in an extraction column. In some examples, a temperature of the granulation liquid before being fed into an extraction liquid stream is lower than a temperature of the extraction liquid stream before the granulation liquid is fed into the extraction liquid stream. The invention relates also to a device for carrying out processes such as this one.
156 WATER DISPERSIBLE POLYAMIDE BUILDING BLOCKS US15535946 2015-12-14 US20180002484A1 2018-01-04 Anthony D. Pajerski; Gabor Erdodi; Naser Pourahmady
Water dispersible polyamides having carboxylic acid groups are disclosed. These are made by reacting polycarboxyl is acids or anhydrides thereof with amine containing monomer or an amide terminated polyamide under reaction conditions such that a few of the carboxylic acid groups are residual and can promote dispersion in water. These polyamides after dispersion can be chain extended to higher molecular weight polymers or can be terminally functionalized with reactive groups such as isocyanate, epoxy, vinyl, acetoacetonate, or silanol groups. Composites and hybrids of these polyamides with vinyl polymers are also disclosed and claimed.

The present invention relates to a composite semipermeable membrane including a supporting membrane and a separation functional layer disposed on the supporting membrane, in which the separation functional layer comprises an aromatic polyamide, the aromatic polyamide has side chains and terminal groups, at least one of the side chains and terminal groups of the aromatic polyamide being an amino group, at least one of the side chains and terminal groups of the aromatic polyamide is a substituent having a structure represented by formula (1): —NXY or formula (2): —NXYZ, and in the aromatic polyamide, a content A of substituents having structures represented by formula (1) and formula (2) and a content B of amide groups satisfy 0.005≦A/B≦0.15.

In an example, a process of forming a photoisomerizing azobenzene polymer includes chemically reacting an azobenzene material that includes at least two chlorocarbonyl functional groups with an amine to form a photoisomerizing azobenzene polymer. The photoisomerizing azobenzene polymer has a polymer chain that includes a first chlorocarbonyl group disposed at a first end of the polymer chain, a plurality of repeating azobenzene monomer units, and a second chlorocarbonyl group disposed at a second end of the polymer chain.
