PROCESS FOR REPOLYMERIZATION OF POLYMERIC MATERIALS

Polymeric materials are repolymerized by intensely admixing the polymer with an additive having the formula: wherein M is titanium or zirconium, R, R and R are each a monovalent alkyl, alkenyl, alkynyl, aralkyl, aryl or alkaryl group having up to 20 carbon atoms or a halogen or ether substituted der...

Beschreibung
Zusammenfassung:	Polymeric materials are repolymerized by intensely admixing the polymer with an additive having the formula: wherein M is titanium or zirconium, R, R and R are each a monovalent alkyl, alkenyl, alkynyl, aralkyl, aryl or alkaryl group having up to 20 carbon atoms or a halogen or ether substituted derivative thereof, and, in addition, R may also by an oxy derivative or an ether substituted oxy derivative of said groups; A, B, and C are each a monovalent aroxy, thioaroxy, diester phosphate, diester pyrophosphate, oxyalkylamino, sulfonyl or carboxyl containing up to 30 carbon atoms; and a + b + c = 3. The repolymerized polymers have improved physical properties and higher heat distortion temperatures, experience less thermal degradation and show greater solvolysis resistance than the polymers prior to the repolymerization.
