SynopsisGlycoluril is an organic chemical composed of two cyclic urea groups joined across the same two-carbon chain. It is a white powder that has been used in water treatment, in paints and coatings, and occasionally as a slow-release fertilizer. Market.....
SynopsisPolyamide block copolymers (COPAs) are high-performance, light-weight thermoplastic elastomers based on polyester-amide (PEA), polyether-esteramide (PEEA), or polyether-amide (PEBA) block copolymers. The polyamide portion forms the hard (thermoplastic) domains.....
SynopsisPolyvinyl chloride acetate (PVCA) is a transparent, mostly amorphous thermoplastic copolymer of about 80-95% vinyl chloride and 5-20% vinyl acetate. PVAC resins have high transparency, are odor- and tasteless, and are very tough, and durable. These resins also.....
SynopsisPolyvinylidene dichloride (PVDC), also called polyvinylidene chloride, is a clear, semi-crystalline thermoplastic produced by addition polymerization of 1,1-dichloroethylene. Films made from PVDC are optically clear, have high degree of gloss and low gas perme.....
SynopsisBisphenol A diglycidyl ether (commonly abbreviated BADGE or DGEBA) is an organic compound used as constituent of epoxy resins. The compound is a colorless solid (commercial samples can appear yellow) that melts slightly above room temperature. Mar.....
SynopsisPerfluorinated polymers are produced from alkenes in which hydrogen atoms have been replaced by fluorine. Perfluorinated polymers have excellent chemical resistance and weatherability including UV and ozone resistance which increases with the number of fluorin.....
SynopsisPolyhydroxy ethers are high molecular weight thermoplastic polymers and thermosetting resins of epichlorohydrin and bisphenol A. These polymers have terminal hydroxyl groups as well as hydroxyl groups in every repeat unit. They are usually blended and heat cur.....
SynopsisPolyphosphazenes, an emerging class of polymers, include macromolecules, which have been proven to be biocompatible, biodegradable, and bioactive. Their unprecedented structural diversity and unique properties make them suitable as vaccine adjuvants, microenca.....
SynopsisAnionic starches can be prepared by treating an aqueous starch slurry or semi-dry starch paste with an oxidizing agent such as hydrogen peroxide, ammonium persulfate, or sodium hypochlorite under alkaline conditions and at ambient or slightly elevated temperat.....
SynopsisPhthalonitriles (PN) are a relative new class of commercial high performance engineering thermosets.1 The resins can be prepared by nitro-displacement of nitro-phthalonitriles with phenoxyphenols in the presence of a base. The resulting resins are typically cu.....
