ABSTRACT:
Novel poly(B-alkenyl-borazines), such as poly(B-vinyl borazine), are useful as precursors to BN ceramics. The poly alkenylborazines, which may advantageously be soluble and easily processed, are prepared by heat treatment of corresponding B-alkenylborazines, which are themselves novel compounds.
