Collection: Polymers

Polymers — includes natural polymers such as lignin, chitin, alginate, and polysaccharides derived from plants or animals, as well as synthetic polymers such as polyacrylamide, which are used as raw materials or supporting materials in various materials research.

Natural polymers such as carboxymethyl cellulose, amylopectin, and chondroitin sulfate are used by materials chemistry and biomaterials researchers to formulate hydrogels, thickeners, and delivery matrices, while synthetic polymers such as polyacrylamide are used as test materials for electrophoresis, flocculants, or film-forming materials. Variations in molecular weight and degree of substitution affect the viscosity and mechanical properties of the resulting solutions or gels.

Example products in this collection: TCI L0082 8061-51-6 Lignin (Alkaline), TCI C0045 9004-32-4 Carboxymethyl Cellulose Sodium Salt (n=approx. 500), TCI A0456 9037-22-3 Amylopectin (Amylose free), from Waxy Corn, TCI C0072 1398-61-4 Chitin, TCI A0205 9005-38-3 Sodium Alginate 100-200, TCI C0335 9082-07-9 Chondroitin Sulfate Sodium Salt, TCI A0140 9003-05-8 Acrylamide Polymer (containing small amounts of formalin as fungicide) (10% in Water), TCI C0603 9004-32-4 Carboxymethyl Cellulose Sodium Salt (n=approx. 1,050).

Please note the molecular weight or degree of polymerization (expressed as the n value), the viscosity grade, and the natural source, as these determine solution characteristics and suitability for the intended application. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
