Ring-opened 4-hydroxy-δ-valerolactone subunit as a key structural fragment of polyesters that degrade without acid formation
摘要:
Random copolymers of C-caprolactone with O-benzyl-protected 4-hydroxy- or 2,4-dihydroxy-delta-valerolactone after hydrogenation form gamma-hydroxy functionalized polyesters that degrade via the cyclization to gamma-butyrolactone fragments without carboxylic acid formation.
