Abstract


Investigation influence of methods obtaining polymer compositions based on thermostable polymers (aromatic polyamide, fluoropolymer and phenoplast) and dispersed silica on quality of their compound. It had been investigated quality of compound of initial components of polymer compositions based on thermostable polymers according to methods of obtaining it. This parameter had been estimate by uniform distributions of fillers in polymer compositions with help thermal method and microscopy. Investigation data’s had been process with help of methods of mathematical statistics. They are represented in the form of graphical and mathematical dependencies. It had been founded optimal time of mixing initial components of polymer compositions made by mechanical methods of compounding. It had been established that mixing time depend on concentration of dispersed filler in polymers. Based of result of investigations had been obtained mathematical dependences, that describe influence of concentration of initial components in polymer compositions on their mixing time. It had been founded quality of distribution of initial component of compositions made by physicochemical (in situ) method. It had been established influence of concentration of initial components in polymer compositions on quality of their distribution. It had been established regularity of dependence of methods of obtaining polymer composition based on thermostable polymers on quality of compound their initial components. It had been founded optimal technological parameters of compound the initial components of thermostable polymer compositions. And it had been founded optimal methods of their obtaining.
