Course detail
Polymers
FSI-WPLAcad. year: 2018/2019
This subject deals with materials, which in many applications replace classical materials and together with technical glasses and ceramics create a new class of modern constructional materials. Attention is paid to: molecular structure and molecular weight of polymers, transition
temperatures; viscoelasticity, reological models, stress-strain behaviour, influences of strain rate, of temperature and of time on mechanical properties of polymers, time-temperature superposition, degradation and ageing; polymeric composites, anisotropy of their properties, production and applications; basic types of plastics, their properties and applications; technology of processing and principles of designing of plastic products; plastics and environment, resources of leavings, trends in waste recycling, recycling of plastics to polymers and low-molecular products, burning of plastics.

Examination: The first – written – part: the orientation of student in the whole taken through subject matter is checked up by means of 30 questions. Every answer has rate of 5 points in the best occasion, so it is possible to gain 150 points maximally. Acquisition of less then 75 points means the failing. Student, who gains more then 76 points, passes to the second – oral – part of exam with rating “sufficient/E” in case of acquirement from 76 to 90 points, “satisfactory/D” – from 91 to 105 points, “good/C” – from 106 to 120 point, “very good/B” – from 121 to 135 points and “excellent/A” – from 136 to 150 point. In oral part of exam the student demonstrates the quality and depth of his knowledge in areas determined by examiner. Resulting evaluation of student considers his evaluation from practice and involves results from written and oral part of exam.
