Description:
|
Introduction to the polymer blends like multiphase systems, preparation and properties of blends. Knowledge of this topic is important for the development of the new polymer systems.
THE CONTENTS OF THE COURSE:
1st week: Historical outline of the development of polymer blends. Introduction to the
polymer blends. Types and classification of polymer blends.
2nd week: Application of polymer blends. Structure and properties of polymer blends.
Miscibility of polymer blends, parameters important for miscibility.
3rd week: The reasons for blending and how to select blend components. The methods
of blend preparation: mechanical mixing, dissolution in solvent,
polymerization, reactive blending.
4th week: Mechanical mixing of polymer blends. Preparation of polymer blends in
extruder. Mixing of polymer blends in Brabender mixer. The influence of
temperature, composition and ratio of components on the miscibility.
5th week: 1st partial test
6th week: Moulding of polymer blends. Moulding in mould. Injection moulding.
7th week: Miscible and immiscible polymer blends. Determination of polymer/polymer
miscibility by DSC and DMA technique.
8th week: Crystalline and morphological structure of polymer blends. Kinetic of
crystallization, isothermal and nonisothermal.
9th week: Reactive and nonreactive compatibilization. Compatibilization of polymer
blends with mineral fillers.
10th week: 2nd partial test
11th week: Time-temperature superposition. Oxidative and thermal stability of polymer
blends.
