Abstract:
A novel process of manufacturing sevelamer carbonate from a polyallylamine carbonate or bicarbonate chloride salt. Processes for manufacture of carbonate and/or bicarbonate salts of water insoluble polymers containing amino groups that are useful as anion binders in the gastrointestinal (Gl) system. The process arranges the polyallylamine chain in a solution in such a way that the cross-linking reaction with epichlorohydrin can be controlled at a desired reaction rate.

Abstract:
A nanocomposite material containing several necessary components. The first component is from 98.9 to 70 parts by weight of a bulk polymer, the bulk polymer being a non-polar polymer, such as polyethylene or polypropylene. The second component is from 1 to 30 parts by weight of a cation exchanging multi-layered silicate material, such as acid or quaternary ammonium treated montmorillonite or sepiolite, dispersed in the bulk polymer, the cation exchanging multi-layered silicate material having a plurality of anionic sites, the multi-layered silicate material being exfoliated to one, two, three, four and more than four layer units, the number percent of the one, two, three and four layer units being greater than the number percent of the more than four layer units. The third component is from 0.1 to 10 parts by weight of an organic cation, such as polyethylene or polypropylene terminated by an amine group, the organic cation having a pendent polymer chain, the polymer of the pendent polymer chain being miscible with the bulk polymer, the average molecular weight of the pendent polymer chain being more than 3000. The nanocomposite material is made by blending the molten bulk polymer with the cation exchanging multi-layered silicate material and the organic cation.
Abstract:
The present invention relates to a process comprising reacting an aminated polyolefin with a polyketone polymer. Preferably, the aminated polyolefin has been obtained by reacting a polyolefin containing carboxylic acid groups, e.g. a polyolefin which has been modified with carboxylic acid containing compounds, with a compound containing at least 2 amine groups. Further, the invention relates to a composition obtainable by such process, to a composition based on an aminated polyolefin and a polyketone polymer, to an aminated polyolefin and to laminates and blends comprising such composition.
