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:
Acetamide Acetamide (systematic name: ethanamide) is an organic compound with the formula CHCONH. It is the simplest amide derived from acetic acid. It finds some use as a plasticizer and as an industrial solvent. The related compound "N","N"-dimethylacetamide (DMA) is more widely used, but it is not prepared from acetamide.
