Method of anionic polymerization and copolymerization of lactam of {107 -aminocarboxylic acids
Abstract
Abstract Method of anionic polymerization and copolymerization of lactams of omega -aminocarboxylic acids, wherein alkali metal alkoxyhydroaluminates are used as basic catalysts, with or without usual activators. Alkali metal alkoxyhydroaluminates (complex alkoxyhydrides of aluminium and alkali metal) posses the general formula Me AL HaZ(4 a) WHEREIN Me is an alkali metal atom, a is an integer ranging from 0 to 3 and Z is a group -O-A-X-Rm or -C-R, R being a lower alkyl, A being -CR1R2-(CH2)n-, R1 and R2 standing for either a hydrogen atom or a methyl group, n being an integer ranging from 2 to 6 and X standing for oxygen, sulphur or nitrogen, and m being 1 in case of oxygen and sulphur and 2 in case of nitrogen. Said complex alkoxyhydroaluminates are capable of forming alkali metal salts of lactams and the respective lactams anions.
