ABSTRACT:
Polyamides comprising substantial amounts of Nylon-11 and/or Nylon-12 units are cross-linked by irradiation in the presence of an unsaturated cross-linking agent, preferably triallyl isocyanurate. The cross-linked products are particularly useful in the form of heat-recoverable shaped articles, e.g. heat-shrinkable tubing.
