The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

SINOPSIS

Composite rocket propellants with improved insensitive munitions (IM) characteristics can be produced using cross-linked hydroxyl-terminated polyether (HTPE) binders and are potential alternatives to hydroxyl-terminated polybutadiene (HTPB) compositions. Some characteristics of propellants based on the HTPE binder have been presented, but there has been no report on the comprehensive chemical characterization of the prepolymer. In this paper we report a preliminary study on the characterization and comparison of two different HTPE prepolymers, one synthesized in our laboratory and the other obtained from a commercial source. Analyses were carried out on the two materials to determine molecular weight, molecular structure, glass transition temperature (Tg), melting temperature (Tm), impurities, and viscosity. These properties were determined using a range of techniques, including size-exclusion chromatography (SEC), nuclear magnetic resonance (NMR) spectroscopy, differential scanning calorimetry (DSC), gas chromatography-mass spectrometry (GC-MS), and Fourier transform infrared (FTIR) spectroscopy.
