Abstract: A process for lessening shear-induced reduction of fiber length in a melt processable, fiber reinforced polymer composition, and compositions useful in and obtained from such process, comprising the steps of: admixing a first polymer, the first polymer being a thermoplastic polymer, with a second polymer being TLCP, and a reinforcing fiber; and subjecting the composition to shear, wherein the first and second polymers have melt processing ranges that overlap over an overlapping melt processing range; and the second polymer is partly immiscible with or immiscible with the first polymer when mixed with the first polymer within the overlapping melt processing range.

Abstract: Disclosed is a process for the preparation of ketones by contacting one or more carboxylic acids with a niobium catalyst at elevated temperatures. The process includes the use of a modified base-exchanged niobium catalyst that is particularly useful for the production of cyclopropyl ketones such as cyclopropyl methyl ketone from cyclopropanecarboxylic acid and acetic acid.

Abstract: A method for providing a standard Raman spectrum from a sample uses a particular Raman spectrometry apparatus or any similar Raman spectrometry apparatus, which is used to simultaneously irradiate a reference material and at least one sample, thereby obtaining their respective convolved Raman spectra. Using a defined standard energy dispersion characteristic and a standard Raman spectrum of the reference material, a convolution function is determined and applied to produce a deconvolved Raman spectrum of the sample. This deconvolved spectrum is multiplied by a defined standard photometric response function to produce a standard Raman spectrum of the sample.
