Roles of alkoxy titanates and zirconates as multifunctional agents for polymers (in English)

Polimery 2004, No 3, 159


Summary

A review discusses the roles of novel alkoxy titanates and zirconates as additives for polymers. As coupling agents, they chemically bond inorganic as well as organic fillers and polymers via proton coordination without the need of water of condensation as for alkoxysilanes. Thermally stable alkoxy titanates and zirconates function also as in-situ polymerization and copolymerization catalysts for filled or unfilled polymers during the plasticization resulting in their significantly faster thermoplastic processing at lower temperatures. The catalysis effect is permanent even in recycling. Novel trialkoxy zirconates are shown to be transparent, permanent, non-blooming and non-moisture dependent multifunctional agents.


Keywords: alkoxy titanates, alkoxy zirconates, adhesion promoters, catalysts, crosslinking agents, mechanical and processing properties of polymers
