Bisoxazolone based polymers

摘要

A method of preparing an elastomeric polymer comprising the step of reacting a bisoxazolone with a primary or secondary di-amine terminated oligomer. Also disclosed is a polymer having the formula comprising the repeat unit (I), where R₁, R₂, R₃ and R₄ can be any alkyl or aryl groups and R₅ the amine terminated oligomer
