Patents Assigned to DSM RIM Nylon VOF
  • Lactam polymerization initiators
    Patent number: 4677189
    Abstract: Disclosed are lactam polymerization initiators comprising at least two lactam terminal groups of the formula: ##STR1## wherein Q is a lactam residue containing a C.sub.3 to C.sub.11 alkylene group and is bonded to a carbonyl through the nitrogen atom of the lactam; A is an aliphatic or aromatic hydrocarbyl or hydrocarbyl ether group; m is 0 or 1; when m is 0, n is 0 or 1 and p is 1; when m is 1, n is in the range of 1 to 3 and p=n; and an elastomeric backbone derived from a telechelic polyamine containing at least two primary or secondary amine groups. Also disclosed are a process for forming the same; nylon block copolymers produced therefrom; and a process for the polymerization thereof.

  • Stabilized lactam polymerization solutions
    Patent number: 4672085
    Abstract: Unsaturated oligomers and solutions thereof are stabilized with a trisubstituted urea to provide improved storage stability. The stabilized unsaturated oligomer solutions are useful in lactam polymerization processes which yield nylon block copolymers containing unsaturated oligomer segments. The unsaturated oligomers disclosed herein have at least 4 carbons and have pendant thereto at least one hydroxy, amine, epoxy, acyllactam, or acyllactam precursor group.
