Influence of the processing temperature and of the compatibilizing agent on the rheologicalbehavior of high density polyethylene-based composites charged with calium carbonate.II.the elasticcomponent

摘要

The paper discusses the results of some ample studies,devoted to the influence of processing temperature and of the amount of compatibilization agent on the elastic component of some high density polyethylene (HDPE)-based composites charged with calcium carbonate.Basedon a calculation algorithm of their own,and starting from the output presure from the rheological nozzle,determined experimentally,the authors realized the rheological characterization of the elastic component of HDPE melts charged with calcium carbonate.It was demonstrated that the processing temperature influences considerably the elastic componnet of the analyzed compounds,while the application of a suitable procesing temperature,compounds,while the application of a suitable processing temperature,combined with an optimum ratio of compatibilization agent led to the obtention of some thermoplastic composites evidencing the elastic behavior of some thermoplastic alloys.
