ABSTRACT:
Compositions are described, which are blow-moldable into shaped articles, comprising a reaction product between polycaprolactam, aminoalkyltrialkoxysilane and a catalytic amount of water. The compositions have a melt index of about 2.25 g/10 min. or below and are substantially free of trialkoxysilane groups. Preferred compositions also contain ethylene/vinyl acetate copolymer as an impact modifier to increase the impact strength of blow-molded articles made therefrom, such as bottles.
