Abstract of the Disclosure A composition particularly adapted for use in a rotational moulding process is disclosed. The composition comprises polyethylene having a density of 0.920 - 0.970 g/cm3 and a melt index of 10-35 dg/min., 0.3 - 1.3% by weight of a bis(tert. alkyl peroxyalkyl) benzene, 0.2 - 1.5% by weight of a co-curing agent selected from triallyl cyanurate, triallyl isocyanurate and 1,2 - polybutadiene, 0.01 - 0.05% by weight of a hindered phenolic antioxidant and 0.01 - 0.02% by weight of a secondary antioxidant. The preferred secondary antioxidant is tris di(tert.-butyl phenyl) phosphite. The composition may be used in for example, the moulding of tanks, barrels, containers and the like. |
