ABSTRACT:
Chlorinated polyvinyl chloride resins when crosslinked have improved melt strength in comparison with non-crosslinked chlorinated polyvinyl chloride resins. Moreover, the crosslinked chlorinated polyvinyl chloride resins have unexpected improved processing properties such as reduced processing torgue in comparison with crosslinked polyvinyl chloride resins which upon crosslinking exhibit increased processing torque. Various amounts of non-crosslinked chlorinated polyvinyl chloride and/or non-crosslinked polyvinyl chloride which does not affect said improved properties can be blended with the cross-linked chlorinated polyvinyl chloride resins.
