    • Polymeric materials are repolymerized by intensely admixing the polymer with an additive having the formula: ##STR1## wherein M is titanium or zirconium, R, R.sup.1 and R.sup.2 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.sup.2 may also be 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.
    • 通过将聚合物与具有下式的添加剂强烈混合来聚合高分子材料:其中M是钛或锆,R,R 1和R 2各自是一价烷基,烯基,炔基,芳烷基,芳基或烷芳基,其具有至多 20个碳原子或其卤素或醚取代的衍生物,另外,R 2也可以是所述基团的氧基衍生物或醚取代的氧基衍生物; A,B和C各自是含有至多30个碳原子的单价芳氧基,硫代羟基,二酯磷酸酯,二酯焦磷酸酯,氧烷基氨基,磺酰基或羧基; 和a + b + c = 3。 所述重聚聚合物具有改善的物理性能和较高的热变形温度,经历较少的热降解,并且显示比在再聚合之前的聚合物更大的溶剂分解性。
