Lactam-polyol-polyacyl lactam block terpolymers having both ester linkages and amide linkages between the monomeric segments of the terpolymer are disclosed. Also disclosed is a process for preparing the above block terpolymers comprising reacting together a lactam, polyol and polyacyl lactam in the presence of a basic lactam polymerization catalyst to form a lactam-polyol-polyacyl lactam block terpolymer.
