Abstract
A process for producing a chemically crosslinked polyethylene foam, which comprises heating a polyethylene composition consisting essentially of 97 to 50 % by weight of polyethylene, 3 to 50 % by weight of polybutadiene having a 1,2-addition unit content of at least 70 %, an intrinsic viscosity [.eta.] of at least 0.7 dl/g (as measured in toluene at 30.degree. C), at least one blowing agent and at least one crosslinking agent to foam and crosslink said polyethylene composition. The above process can be carried out with a smaller amount of crosslinking agents without expensive crosslinking equipment, and the foam obtained by this process has improved physical properties.
