Gelled premixes based on heat-resistant polymers and polyvinyl chloride-based compositions containing such gelled premixes

摘要

Gelled premixes based on heat-resistant polymers whose Vicat softening point is higher than 100 DEG C., containing an impact strength improver and a lubricant for polyvinyl chloride and polyvinyl chloride-based compositions containing such gelled premixes. The incorporation of heat-resistant polymers in the form of gelled premixes results in perfectly homogeneous polyvinyl chloride-based compositions which are converted without any problems at the usual temperatures for processing polyvinyl chloride into shaped articles with improved heat resistance.
