In vitro evaluation of human mesenchymal stem cell neural differentiation on tyrsine-derived polyarylates and polycarbonates
… surface of tyrosine-derived polycarbonates and polyarylates on MSC differentiation along the neural lineage were investigated in this research. These polymers were developed by Dr. Joachim Kohn, where by altering the length of the alkyl ester pendent chain and the backbone composition, these …

Synthesis and characterization of high performance polymeric materials: poly(arylene ethers), polyamides, polyesters and liquid crystalline polyarylates
… specimen. Novel star-branched liquid crystalline polyarylates (LCP) were made via melt acidolysis which were subsequently transformed to liquid crystalline foams by supersaturation of carbon dioxide followed by thermal blowing. It was found that the AB type monomers were essential to generate star …

An in vitro evaluation of tyrosine derived polyarylates and polycarbonate as polymeric scaffold for human mesenchymal stem cells osteogenic differentiation
… as potential scaffolds. Polycarbonates and polyarylates have combinatorial libraries that exhibit a range of surface chemistries leading to changes in the surface properties such as wettability, rigidity and protein adsorption. Structural modifications of their pendant chain and backbone …

Growth behavior of fibroblasts influenced by small changes in polymer structure
… study is aimed at comparing cell growth on polyarylates with that of polylactic acid in their original state or by introducing small changes in the surface structure of the polymers, by adopting different processing techniques (i.e. drawn and undrawn forms). Though, it is the most widely …

Process-structure-property relationships of resorbable desamino tyrosine derived polymers : effect of backbone chemistry and assembly on drug delivery
… the behavior of the tyrosine derived polyarylates under in vitro conditions. The change of structure caused by incubation in phosphate buffer solution and the effect on the release of p-nitroaniline (PNA) (model drug) has been investigated, primarily with differential scanning …

Synthesis and characterization of polyether-ester liquid crystalline polyesters and poly(arylene ether ketone)-lcp segmented copolymers
… and segmented copolymers. A variety of polyarylates based on 5-tertiary butylisophthalic acid were synthesized via melt acidolysis techniques. The resulting high molecular weight polyarylates were amorphous polymers and the t-butyl groups along the polymer backbones were found to be …

Synthesis and Characterization of Multicomponent Polyesters via Step-growth Polymerization
… Moreover, an efficient approach to hyperbranched polyarylates via the polymerization of A2 and B3 monomers without gelation was also developed. A dilute bisphenol A (A2) solution was added slowly to a dilute 1,3,5-benzenetricarbonyl trichloride (B3) solution at 25 °C to prepare hyperbranched …
