Abstract
A recyclable crosslinked polymeric foam includes a reaction product of 0.1 to 10 parts by weight of a crosslinking agent and 0.1 to 5 parts by weight of a radical initiator, based on 100 parts by weight of a polymeric material. The crosslinking agent is represented by the following formula: wherein R is an alkylene group having 2 to 10 carbon atoms, an arylene group having 6 to 18 carbon atoms, or a cycloalkylene group having 6 to 18 carbon atoms.
