Abstract

See full text

Acido-basic properties of a system containing a polymer obtained by decomposing by oxidative cleavage of a carbon-carbon double bond, and a trifunctional molecule having an alkoxysilyl group in the structure as represented by the formula (A) are changed such that the system is changed into a basic system when the system is acidic and the system is changed into an acidic system when the system is basic to combine the decomposed polymer and the trifunctional molecule, thereby introducing the alkoxysilyl group into the main chain. Furthermore, acido-basic properties of a system containing a polymer obtained by decomposing by oxidative cleavage of a carbon-carbon double bond to decrease the molecular weight, and a functional molecule having an alkoxysilyl group as represented by the formula (a) are changed in the same manner as above to combine the decomposed polymer and the functional molecule, thereby introducing the alkoxysilyl group in a molecular terminal.
