TL;DR: The composites of jute fabrics (hessian cloth) and polycarbonate were prepared by compression molding The jute surface was modified with γ-aminopropyl trimethoxy silane (Z-6011) to improve interfacial adhesion between jute and poly carbonate as discussed by the authors.
Abstract: The composites of jute fabrics (hessian cloth) and polycarbonate were prepared by compression molding The jute surface was modified with γ-aminopropyl trimethoxy silane (Z-6011) to improve interfacial adhesion between jute and polycarbonate The treated and untreated jute surfaces as well as composites were investigated by X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, Environmental scanning electron microscopy, Dynamic mechanical analysis, and mechanical testing XPS and FTIR assure that the silane plays important role to form interfacial bonding with the jute fibers and polycarbonate The surface topography of silanized and virgin fibers, and the interfacial adhesion properties of the composite were investigated by ESEM DMA analysis shows the improved storage and loss moduli of silanized jute composite as compared to the untreated one The modified jute composite also produces enhanced mechanical properties © 2006 Wiley Periodicals, Inc J Appl Polym Sci 100: 4142–4154, 2006

TL;DR: In this paper, the equilibrium phase behavior of binary blends of various polycarbonates (PC) with polystyrene (PS), poly(methyl methacrylate) (PMMA), bisphenol A polycarbonate and tetramethylbisphernol Apolycarbonate is studied.
Abstract: The equilibrium phase behavior of binary blends of various polycarbonates (PC) with polystyrene (PS), poly(methyl methacrylate) (PMMA), bisphenol A polycarbonate and tetramethylbisphernol A polycarbonate is studied. The variations in PC structure primarily involved substitutions onto the phenyl rings, or both, of the bisphenol monomer. Polar connector groups promote favorable interactions with PMMA while ring substitution with methyl groups improves miscibility with PS. Other structural changes in the connector group or on the phenyl rings can act against the miscibility of PC with PMMA or PS

TL;DR: In this paper, a nonphosgene process for producing bisphenol-A polycarbonate (PC) was developed through a transesterification between BPA and dimethyl carbonate (DMC) and a melt-polycondensation of the resulting bismethylcarbonate.
Abstract: A novel nonphosgene process for producing bisphenol-A polycarbonate (PC) was developed through a transesterification between bisphenol-A (BPA) and dimethyl carbonate (DMC) and a melt-polycondensation of the resulting bisphenol-A bismethylcarbonate (1). The transesterification was carried out by heating bisphenol A in dimethylcarbonate in the presence of Lewis acid catalysts, removing the by-producing methanol using molecular shieves 4A. Among various catalysts, a combination of (Bu2SnCl)2O and dimethylaminopyridine gave the best results to produce 1 in 22% yield for 48 h. Using a larger amount of the molecular sieves further improved the yield to 80% in 120 h. The resulting 1 was heated under reduced pressure in the presence of titanium catalysts to produce PC in good yields. The resulting PC had high weight average molecular weight (Mw) of 75,000. © 1999 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 37: 2087–2093, 1999
