Disclosed are conversion products of N-substituted carbamoyllactam functional compounds characterized by the general formula:
where:
A represents an oxygen atom or an NH group;
R represents an alkyl, aralkyl, alkaryl or aryl group, where alkyl and alkyl bound in aralkyl or alkaryl may also be cycloalkyl;
P represents a residue of a compound P(AH)x with a number average molecular weight of at least 150, with one or more OH or NH₂ groups, P(AH)x being a liquid crystalline compound or a compound with liquid crystalline segments in the main chain and/or the side chain, or a compound which forms with lactam-blocked polyisocyanate a compound with liquid crystalline properties;
(-L-) represents an opened lactam ring;
(-L) represents a non-opened lactam ring;
x is a whole number higher than or equal to 1;
y is equal to 0 or 1; and
a is a whole number higher than or equal to 1.
Further, the present invention relates to polylactam block copolymers obtained by lactam polymerization at a lactam group.
