| 摘要 |
Polymeric materials are prepared by polymerizing an organic compound containing at least two labile hydrogens in the presence of a zirconium, hafnium or titanium halide. The labile hydrogen atoms are provided by amides, including aminoplasts, carboxylic acids, polyhydroxy compounds or other compounds capable of forming reactive complexes with zirconium, hafnium and titanium halides. Aqueous media can be employed.
