POLYMER-INORGANIC COMPOSITES PRODUCED BY MATRIX CONDENSATION OF TITANIUM(IV) HYDROXIDE IN THE PRESENCE OF POLYETHYLENE-GLYCOL

Based on the methods of matrix polymerization, the synthesis of a poly mer-inorganic composite (polyethylene glycol-titanium hydroxide) was c onducted via the hydrolysis of tetraoxyisopropylbutane and titanium te traoxy-n-butyl. Solutions of the macromolecular matrix of polyethylene glycol in benzene were used for the reaction, which resulted in the f ormation of a transparent gel. This suggests that a composite was (sic ) that contained only minute particles of titanium hydroxide. The comp osites obtained were characterized by a relatively low degree of cryst allinity and a low melting temperature as compared with the ethylene g lycol. The melting temperature of the composite depended on the synthe sis conditions, but did not change after cyclic heating and cooling wi th the temperature varying between 25 and 120-degrees-C. The formation of the composite was described in terms of the matrix polymerization model. Mutual ''recognition'' of the macromolecular matrix and the cen ters of the newly formed phase was shown to be of great importance for the formation of polymer-particle complexes.
