ELASTOMERE IN FORM VON THERMOPLASTISCHEN COPOLYMERISATEN

摘要

Novel thermoplastic elastomers are disclosed, which are based on copolyesteramides and are composed by a statistically distributed array of soft and hard molecular chains, bonded to each other by ester bonds. Those thermoplastic elastomers have shown an improved resistances to heat and hydrocarbonaceous fluids as fuels, lubricants and like.
