Siloxane-amide block copolymer and process for producing the same |
摘要 |
A siloxane-amide block copolymer represented by formula (I): <IMAGE> (I) <IMAGE> wherein the symbols are as defined in the specification, is disclosed. The polymer of formula (I) is produced by reacting a polycondensate of a diaminosiloxane and a dicarboxylic acid dihalide with an epoxysilane to induce ring-opening addition reaction between the terminal amino groups of the polymer and the epoxy group of the epoxysilane. The siloxane-amide block copolymer exhibits excellent processability and reactive curability due to the hydrolyzable silyl groups at the both terminals.
