Characterization of polyurethane networks structure and properties based on rapeseed oil derived polyol.

Highlights: [•] PU show high E and σt with increasing cohesion energy density. [•] PU networks show higher σt with decreasing Mc . [•] H-bonding is higher in PU with increased urethane group concentration. [•] Formation of cross-links interferes H-bonding. [•] With increasing Mc thermal decomposition of PU began at lower temperature. [ABSTRACT FROM AUTHOR]
