Review on the Impact of Polyols on the Properties of Bio-Based Polyesters

Abstract

Bio-based polyol polyesters are biodegradable elastomers having potential utility in soft tissue engineering. This class of polymers can serve a wide range of biomedical applications. Materials based on these polymers are inherently susceptible to degradation during the period of implantation. Factors that influence the physicochemical properties of polyol polyesters might be useful in achieving a balance between durability and biodegradability. The characterization of these polyol polyesters, together with recent comparative studies involving creative synthesis, mechanical testing, and degradation, have revealed many of their molecular-level differences. The impact of the polyol component on the properties of these bio-based polyesters and the optimal reaction conditions for their synthesis are only now beginning to be resolved. This review describes our current understanding of polyol polyester structural properties as well as a discussion of the more commonly used polyol monomers.

Analysis of the Amorphous and Interphase Influence of Comononomer Loading on Polymer Properties toward Forwarding Bioadvantaged Copolyamides

“…Renewable polyols have been used to produce hydrogels, polyurethanes, and polyesters. [22][23][24][25] The unique functional combinations of these polymers offer the advantages necessary to encourage their adoption. For example, acrylated epoxidized soybean oil has been used to toughen polylactic acid, increase asphalt processability, and reduce asphalt thermal cracking.…”

“…21,26 Polyol polyesters readily biodegrade and are biocompatible. 25 Without these advantages, there would be no impetus for assimilation into the preexisting chemical industry. Attempting to produce legacy polymers from biomass forces competition solely on price, leading to suppressed prices.…”

“…Functionalization of the unsaturated bond with an epoxide and subsequent ring opening with alpha-beta unsaturated carboxylic acids such as acrylic acid and itaconic acid enabled the synthesis of thermosets, rubbers, styrenic block copolymers, and polylactic acid blends. − Polyols have received much attention as well.
