| abstract | A catalyst and initiator composition for lactam polymerization is composed of a Grignard catalyst for lactam polymerization and initiator system containing (a) at least one material represented by the following structural formula: <IMAGE> (b) at least one material represented by the following structural formula: <IMAGE> wherein q and v are independently an integer of at least 1; Z and W are independently selected from a compound or polymeric material, said compound being composed of at least two elements in chemical combination which contain up to two repeating structural units, said polymeric material being a macromolecule formed by the chemical union of at least two coreactants and having at least three repeating structural units; with the proviso that at least a portion of either or both of the materials (a) or (b) is a polymeric material. In the above formulas, R, R', R'', R''' are independently hydrogen, a C1 to C10 aliphatic radical, C3 to C10 cycloaliphatic radical, C6 to C10 aryl or alkaryl radical, and independently R and R'' and the carbon to which each is attached are included as part of a cycloaliphatic or aromatic ring; and Y is an alkylene group having from 3 to 12 carbon atoms or an alkylene group having from 3 to 12 carbon atoms interrupted by a heteroatom. In addition the equivalent ratio of <IMAGE> to th magnesium of the Grignard catalyst is within the range of from 0.3 to 1 to 4 to 1, and at least 10 percent of the initiator groups of initiator system are of the (a) type. |
