TL;DR: These novel blends showed cell adhesion and proliferation comparable to PLAGA, however, the PNEA(50)PhPh( 50) component in the blends was able to increase the phenotypic expression and mineralized matrix synthesis of the primary rat osteoblasts in vitro.

TL;DR: In this article, the distribution of chemical species and the degree of orientation in semicrystalline polymer systems have been studied using fast Fourier transform infrared (FTIR) imaging.
Abstract: The distribution of chemical species and the degree of orientation in semicrystalline polymer systems have been studied using fast Fourier transform infrared (FTIR) imaging. A variety of poly(ethylene glycol) systems, including pure polymer, high and low molecular weight blends, and blends with amorphous polymers, were studied. It is shown that fast FTIR imaging can be used to determine the distribution of species with different molecular weights and can be used to determine the degree of segregation of different components in blends with amorphous polymers. Additionally, by employing an infrared polarizer, the degree of orientation was determined in these systems by the generation of spatially-resolved dichroic ratio images.
