15 صفحه اولLINEAR ALIPHATIC UNSATURATED POLYESTERS BASED ON CIS -2- BUTENE -1,4-DIOL: SYNTHESIS AND CHARACTERIZATION
A new homologous series of linear aliphatic polyesters, such as poly (cis-2- butenylene carboxylate)S, PBms (m is the number of methylene groups in the acid component, m=2-8 have been synthesized by direct polyesterification reactions in anisole, as solvent. FT-IR, 400 MHz H- NMR, C-NMR and elemental analysis were used to establish the structure of polyesters. Molecular weight distributi...
متن کاملIn vivo kinetic degradation analysis and biocompatibility of aliphatic polyester polyurethanes.
Polyester polyurethanes incorporating polyhedral oligosilsesquioxane (POSS) as the crystalline hard block were evaluated for biocompatibility and degradation over 24 weeks in vivo. In vitro studies were also used to predict the onset of mass loss. The molecular weight of each sample was found to decrease quickly over an 8 week period and then became constant due to the nondegrading POSS hard bl...
متن کاملSerological Studies on Azoproteins Antigens Containing Azocomponents with Aliphatic Side
The first studies in this series included only simple aromatic amino compounds. An extension of the investigation to aliphatic substances, such as tartaric acid (1), pepfides (2) and carbohydrates (3, 4), was made possible by the expedient of combining them to aromatic amines to form diazotizable compounds which could be linked to protein. Since simple aliphatic compounds have not been examined...
متن کاملControlling cell adhesion on polyurethanes{
Cell attractive or non-attractive surface properties of polyurethane devices can be controlled by treating them with zirconium tetra(tert-butoxide). This gives reactive interfacial zirconium complex species that can be used subsequently to bond cell attractive peptides such as arg-gly-asp (RGD) or cell non-attractive organics such as polyethylene glycol (PEG) to the device surface. Control of t...
