Influence of processing conditions of poly(ethylene terephthalate)–poly(butylene terephthalate) blends on the dimension of their structure formation space

详细

It was shown that the structure of poly(ethylene terephthalate)–poly(butylene terephthalate) blends is formed in a fractal space whose dimension determines the structural dimension and, thus, the properties of the blends. The change in the type of processing of polymer blends significantly affects the dimension of their structure formation space. The pre-extrusion of the blends forms autohesion contacts between their components, which prevents a sharp decrease in the dimension of the space at subsequent injection molding.
