ABSTRACT:
A method for improving the thermal stability of polymer of ethylene having vinyl unsaturation in which the polymer is admixed with a stabilizing amount of a silane compound represented by the formulae R.sub.2 SiA.sub.2 and R.sub.3 SiA' in which each R is the same or different and is selected from aryl, alkaryl, or aralkyl groups containing from 6 to about 24 carbon atoms, each A is the same or different and is selected from hydrogen, azido, halogen, hydroxy, alkoxy groups in which the alkyl radical contains from 1 to about 10 carbon atoms, and alkenyl of 2 to 6 carbon atoms and one A can be lower alkyl of 1 to 6 carbon atoms with the other A selected from among azido, halogen, hydroxy, and alkoxy, lower alkyl and alkenyl as described above, and A' is selected from among halogen, hydrogen and hydroxy groups. The composition of matter produced thereby. A composition of matter containing a polymer of ethylene and a thermally stabilizing amount of a silane represented by the formulae R.sub.2 SiA.sub.2 and R.sub.3 SiA' in which each R is the same or different and is selected from aryl, alkaryl, or aralkyl groups containing from 6 to about 24 carbon atoms, each A is the same or different and is selected from hydrogen, azido, halogen, hydroxy, alkoxy groups in which the alkyl radical contains from 1 to about 10 carbon atoms, and alkenyl of 2 to 6 carbon atoms and one A can be lower alkyl of 1 to 6 carbon atoms with the other A selected from among azido, halogen, hydroxy, and alkoxy, lower alkyl and alkenyl as described above, and A' is selected from among halogen, hydrogen, and hydroxy groups.
