Synthesis of new polydimethylsiloxane‐polyamide copolymers from phenylene‐bis‐5‐oxazolones and aminopropyl‐terminated polydimethylsiloxane oligomers

Alternating polydimethylsiloxane‐polyamide block copolymers were prepared in dichloromethane or chloroform solution at room temperature from 3‐amino‐n‐propyl‐terminated polydimethylsiloxane oligomers and 2,2′‐p‐phenylenebis(4,4‐dimethyl‐5‐oxazolone). Solution and thermal properties of the polymers were characterized.
