ABSTRACT:
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. These thermoplastic elastomers have shown an improved resistance to heat and hydrocarbonaceous fluids such as fuels, lubricants and the like.
