The NIH 3T3 fibroblast cell line was chosen for this study because it provides a robust and durable platform for investigating common cellular functions attachment, viability, proliferation, cellular properties, membrane states, etc.( 14). Figure 5 illustrates the morphology of mouse fibroblast 3T3 cells cultured on a PCL film and PAOS films. To a first, visual approximation cells grown on the sorbitol-containing polyester films and the PCL control exhibit no morphological differences. This indicates qualitatively comparable biocompatibility between PAOS and PCL. 

In this study, a series of sorbitol-containing polyesters were successfully prepared by lipase-catalyzed condensation polymerization. The polymer films were spin-coated and surface morphology was assessed by AFM. The AFM neasurements found a slight decrease in surface roughness attributed to lower... 

The present authors first demonstrated that lipase CA produced reduced sugar-containing polyesters regioselectively from divinyl sebacate and sorbitol, in which sorbitol was exclusively acylated at the 1 and 6-positions (Scheme 12) [102]. Mannitol and meso-erythritol were also regioselectively polymerized with divinyl sebacate. The enzymatic formation of a high-molecular-weight sorbitol-containing polyester was confirmed by the combinatorial approach [67]. 

Unsaturation within the fatty acid chain did not disturb the process. In the polymerisation of divinyl sebacate and polyol (sorbitol), the regioselectivity was controlled to yield sugar-containing polyesters in which the 1- and 6-positions of sorbitol were regioselectively acylated. 

Polyether foam n. A type of polyurethane foam that has been made by reacting isocyanate with a polyether rather than a polyester or other resin component. For rigid foams, polyethers often used as the propylene oxide adducts of materials such as sorbitol, sucrose, aromatics, diamines, pentaerythritol, and methyl glucoside. These range in hydroxyl numbers from 350 to 600. For flexible foams, polyethers with hydroxyl numbers ranging from 40 to 160 are used. Examples are condensates of polyhydric alcohols such as glycerine, sometimes containing small amounts of ethylene oxide to increase reactivity. 

Use of saturated aliphatic polyesters containing 1.4 3.6-dianhydro-sorbitol moieties as plasticizers of PVC [268].
