A new method is reported for the direct preparation of N-substituted lactams from cycloalkanones. N-(p-nitrobenzenesulfonoxyl) methylamine (CH3NH-OSO2C6H4NO2) was reacted with a series of cycloalkanones to give good yields of N-methyl lactams. An addition-rearrangement pathway accounts for the ring-expanded lactam products. A series of N-alkyl-N-arylsulfonoxyl amines were generated in situ and reacted

Extrudable compositions were prepared comprising poly(propylene) and a liquid additive comprising a lactam group. The compositions can comprise other optional additives that include a polyhemiaminal, antioxidants, UV light absorbers, and surfactants. The extruded compositions have higher percent elongation at break and lower Young's modulus compared to extruded poly(propylene) lacking the liquid additive. These and other property improvements make the extruded compositions attractive for forming field joint coatings for undersea pipeline applications.
