Abstract
Abstract Blends of 30 to 90 weight percent of polyurethane resin and 70 to 10 weight percent of polyvinyl chloride resin are provided with thermal stability by incorporating therein a compound having the formula ##STR1## wherein R 1 is cycloalkyl, alkenyl, aralkyl or alkyl, R 2 and R 3 each are hydrogen, methyl, ethyl or aryl and M is barium, calcium or magnesium.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
108 words
