Process for preparation of expandable styrene polymer containing recycled material

摘要

Expandable styrene polymers (PS) contg. 10-100 wt.% recycled PS also contain homogeneously dispersed polyethylene wax (PE wax). Also claimed are: (i) a process for the prodn. of the above expandable PS by addn. of homogeneously dispersed PE wax; and (ii) PS foam contg. 10-100 wt.% recycled PS plus dispersed PE wax as above.
