| Provided herein is a process for producing a composite material composed of a polymer and the layered silicate constituting the clay mineral being connected to the polymer through ionic bonding. The process comprises contacting a layered clay mineral with a swelling agent in the presence of a dispersion medium, thereby forming a complex, mixing said complex containing said dispersion medium with a monomer, and polymerizing said monomer contained in said mixture. The process permits the economical and efficient production of a composite material in which the layered silicate is uniformly dispersed. | ||||||

The present invention more specifically discloses a process for the synthesis of an aliphatic polyester comprising polymerizing at least one dicarboxylic acid with at least one aliphatic glycol in the presence of (1) at least one phosphorus containing compound which contains at least one trivalent or pentavalent phosphorus atom which is bonded directly to at least one phenyl group, (2) an acid acceptor, and (3) at least one halogenated oganic compound. It is preferred to utilize a polymeric agent having bound acid acceptor groups as the acid acceptor in the process of the present invention. | ||||||
