Polyethylene glycol, one of the chemical components in Polyether block amide serves what purpose?
Polyether block amide Polyether block amide or PEBA is a thermoplastic elastomer (TPE). It is known under the tradename of VESTAMID® E (Evonik Industries), and PEBAX (Arkema). It is a block copolymer obtained by polycondensation of a carboxylic acid polyamide (PA6, PA11, PA12) with an alcohol termination polyether (Polytetramethylene glycol PTMG), PEG). The general chemical structure is:
Polymer engineering Polymer engineering is generally an engineering field that designs, analyses, or modifies polymer materials. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications.
