摘要： An expandable ethylenic or styrenic polymer composition for production of lightly crosslinked foamed polymers and a process for controlling the degree of crosslinking of the polymer prior to extrusion foaming. The control is obtained by use of (a) a reversible gas-yielding crosslinking reaction which is delayed in the foam extrusion line in the presence of gaseous products (alcohols) and (b) added amounts of an alcohol such as an aliphatic alcohol. Suitable crosslinking agents include silanes, azido functional silanes, titanates, and amino compounds.

The foam structures have toughness and elasticity similar to those formed from conventional LLDPE without the poor dimensional stability and foam quality associated with those structures. The foam structures have foam quality similar to those made with conventional LDPE but with enhanced toughness and elasticity.
