  • Method of anionic polymerization of .omega.-aminoacid lactams with alkali metal-Al,B-alkoxy lactamate initiator
    Patent number: 4303778
    Abstract: A method is described for the anionic polymerization and copolymerization of .omega.-aminoacid lactams. This end is attained at elevated temperatures in the presence of a polymerization initiator of the formulaMeZX.sub.m L.sub.nwherein Me is an alkali metal, Z is boron or aluminum, X is an alkoxy group and L is an organic residue derived from a lactam and being of the formula ##STR1## wherein a is an integer in the range 3-11, m is an integer in the range of 0-3, (m+n) is 4 and n is (4-m).
    Type: Grant
