“…[37] Erythritol is a sugar substitute that is approved by the FDA. [69][70][71][72][73][74][75][76] Due to such a wide spectrum of starting materials, the macromolecular characteristics of the poly(erythritol dicarboxylate) (PErD) are diverse. Erythritol is absorbed by the body and excreted unaltered, implying that normal metabolic pathways continue to be unaffected.…”

Polymeric bioelastomers have been explored as alternatives to ceramics and metals in the biomedical fi eld, especially in tissue engineering. Biodegradable aliphatic polyester bioelastomers have become the focus of research because of the ease of synthesis and fabrication in addition to their biodegradation properties. The variety and complexity of tissues in the human body continue to challenge researchers to develop newer biomaterials that are compatible and degradable, and have suitable mechanical profi les. This entry will comprehensively discuss the design specifi cations, the synthetic strategies to be employed in the synthesis of bioelastomers, and their applications in tissue engineering. Further, the entry also elaborates on the recent developments in aliphatic polymeric materials with special emphasis on polyester bioelastomers derived from multifunctional monomers.

“…This is seen upon comparing the values for SAl, AAI and SU1; these values are 48.2, 52.0 and 58.7 0 C respectively. It is well known that the spacing between the sites of cross-linking will occasionally reduce the heat generated from the cross-linking reaction [34,35,36]. In addition to that, the longer molecules are slower in motion and in collisions than shorter ones.…”

Three series of biodegradable unsaturated polyesters containing hydroxybenzoic acid with different ratios and maleic anhydride as a site of unsaturation were synthesized in the presence of several aliphatic acids. Their chemical structures were confirmed via IR and 13 CNMR spectroscopy. Curing exotherms of the unsaturated polyesters with styrene so prepared were determined at several temperatures. Effects of hydroxybenzoic acid content and the percentage of maleic anhydride on the synthesis, structure, curing and mechanical properties and hydrolytic degradation are reported.

“…The utilization of lignocellulosic materials in making composites has received considerable attention, in recent times particularly in thermoplastic composites [5,7,8]. This has been attributed to several advantages offered by lignocelluloses fillers, such as lower density, greater deformability, less abrasiveness to equipment, biodegradability and lower cost [9,10].…”

Abstract. This paper described the effect of empty fruit bunch (EFB) loading in the medium density rigid foam, which was prepared from the palm kernel oil based polyol. The grounded 300Pm EFB fiber was used as filler and its composition were varied from 3, 6, 9 and 12 weight percent. EFB filled PU shown good dimensional stability at 70 0 C and -15 0 C due expending and shrinking percentage are less than 0.8% and 0.4% respectively. The mechanical properties were increased linearly with the EFB loading until it reached an optimum percentage of the EFB. SEM images shows the usage of big size cylindrical particle suggested that the fiber pull out will responsible for the synergistic effect of flexibility and strength of the biofoam produced.
