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.....
SynopsisPolyadipates are aliphatic, medium to ultra-high molecular weight polyesters formed from polyalcohols and adipic acid bny polycondensation. These linear or lightly branched polyester polyols have a low melting and glass transition temperature, high resistance .....
SynopsisAliphatic polyglycols, also called polyether glycols or polyols, are viscous liquids or waxy solids depending on molecular weight and hydroxyl content. The only exception is polyoxymethylene (see Polyacetal) which is a highly crystalline polymer. The three mos.....
SynopsisOxitanes are low molecular weight resins having one or more four-membered rings of three carbon atoms and one oxygen atom. Two very common oxetanes are 3-ethyl-3-hydroxymethyl oxetane (OXA), and 3-Ethyl-3-phenoxymethyloxetane (EHOX). These resins have typicall.....
SynopsisPolynorbornene or polynorbornylene (PNB) is an amorphous, transparent thermoplastic with high glass transition temperature (> 310K). The monomer norbornene is produced via Diels-Alder reaction of ethylene and cyclopentadien and the polymer via ring-opening met.....
SynopsisCyclic olefin polymers are attractive high temperature polymers with outstanding optical properties, good chemical and heat resistance, and excellent dimensional stability. The three most important cyclo olefin monomers are norbornene, cyclopentadiene (CPD), a.....
SynopsisPolyxylylene adipamide, often abbreviated as PA-MXD6, PMXD6 or Nylon-MXD6, is a thermoplastic crystalline polyamide produced by polycondensation of meta-xylylenediamine (MXDA) with adipic acid. Market Analysis and Insights: Global Polyxylylene Adi.....
