Plastics, Rubber and Composites

Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably. The main areas of interest are: •Processing of single and multiphase polymeric systems in quantified, controlled, or novel ways, across the length scales; novel processing technologies; rheology; process measurement, sensors, and control; formation of polymers by novel routes; recycling; choice and incorporation of additives •Properties of these materials; tailoring of properties during processing; property-processing relationships; characterisation of products, across the length scales •Modelling of processing and structure development (melt/solid/multiphase): numerical and analytical modelling; constitutive relationships; validation •Measurement techniques for process control and materials characterisation •Design methodologies, including knowledge based engineering design, and performance of end products

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
