COMBINATION HEAT STABILIZER/LUBRICANT FOR PVC PROCESSING ANDMETHOD FOR PRODUCING THE SAME |
摘要 |
The preparation of a zinc mercaptoacid ester by the reaction of zinc oxide with the mercaptoacid ester in a wax matrix provides an improved heat stabilizer for halogen-containing polymer compositions. The process obviates the necessity of isolating and transporting the normally very viscous zinc mercaptoacid esters. The zinc mercaptoacid ester/wax matrix is also an expedient medium for the preparation and utilization of calcium stearate as a lubricant in the heat stabilizer composition and the stabilized polymer composition containing it. A paraffin wax is the preferred matrix for the preparation and use of the heat stabilizer and lubricant.
