| Abstract: | Biodegradable crosslinked biopolyesters and interpenetrating networks (IPN) were prepared with poly(cardanol fumarate) (MCFR) and poly(castor oil fumarate) (CFR). In addition, polymerization and crosslinking with styrene-free vinyl monomers, vinyl acetate (VA), and n-vinyl pyrrolidone (VP) were adopted to prepare these materials. The IPNs have higher thermal stability and mechanical properties in comparison with the crosslinked biopolyesters. The improved characteristics of IPNs are due to the synergistic effect of physical and chemical crosslinking. These IPNs undergo gradual degradation in various media in comparison with crosslinked biopolyesters. |
