There is a continuing need to produce polymer films with high optical clarity with ability to dial in the optical properties including refractive indices and optical anisotropies. In this research, we investigated the mechano-optical behavior of PMMA/PHB-Cl blend films during uniaxial deformation and mapped out the composition-birefringence-processing relationships. The results indicate the presence...
A new macromonomeric initiator (macroinimer) was synthesized and evaluated for the bulk polymerization of styrene at 60 and 80°C. The macroinimer containing poly(dimethylsiloxane), PDMS, was synthesized via condensation reactions between 4,-4′-azobis-4-cyanopentanoyl chloride (ACPC), PDMS and methacryloyl chloride. The product (MIM I) was thermally homopolymerized and copolymerized with styrene in...
6-Phenylhexanoic acid (6PHxA), 7-phenylheptanoic acid (7PHpA), 9-phenylnonanoic acid (9PNA), 11-phenylundecanoic acid (11PUA), 9-p-tolylnonanoic acid (9TNA) and 9-p-styrylnonanoic acid (9SNA) were prepared and evaluated as substrates for cell growth and polyester production by Pseudomonas oleovorans and Pseudomonas putida. P. putida was more effective than P. oleovorans for producing polyesters from...
