Summary
“Hard-soft” multiblock copolymers,(AB)n type,have been prepared by incorporating rubbery segments into a polyamide 6,10 chain according to a two steps procedure. As soft segments,telechelic polybutadiene or poly(butadiene-co-acrylonitrile) oligomers have been used.The prepared copolymers have been characterized by IR spectroscopy and differential scanning calorimetry. Two different and well defined glass transitions have been observed indicating a phase segregation for the rubbery and polyamide segments.
