The first synthetic organic polymer polyvinylchloride was synthesized in by accidentally. How do polymeric crystals A polymer is a macromolecule (long molecules) built of small covalently bonded units called monomers (“mer” from the Greek word meros meaning part). Karen L. Wooley. The differences between the properties of crystalline organic Chemistry of Polymer Molecules Homopolymer: Only one repeating unit in a single polymer Copolymer: More than one different repeat units in one polymer Polymers are large complex chain molecules made up of `small', `simple' sub-units (monomers) [1, 2, 3, 4]. Plastics: Types – Thermoplastics and Thermosetting plastics. LectureGeneral Introduction to Polymers. Synthetic vs. NPTEL provides E-learning through online and Video courses various streams Fundamentals of Polymer Chemistry. These small units are repeated throughout the macromolecule chain. Watch on. Later, polystyrene was discovered in Course Overview. Consideration of “cradle-to-grave” • A polymer is a macromolecule (long molecules) built of small covalently bonded units called monomers (“mer” from the Greek word meros meaning part). They come in a variety of shapes and g: lecture notes Describe a polymer’s structure in terms of –mer type ordering, tacticity, and backbone chain configuration. Molecular Weight Distribution (MWD) in Equilibrium Step Condensation Polymerizations Chemistry of Polymer Molecules Homopolymer: Only one repeating unit in a single polymer Copolymer: More than one different repeat units in one polymer Functionality: The number of bonds a monomer can form Bifunctional: Can form two new bonds; forms a chain structure Define key terms used in polymer chemistry. Mechanism of polymerization: Free radical mechanism – Cationic mechanism – Anionic mechanism. How are polymer properties effected by molecular weight. Types of polymerization. Example: Polypropylene, trans-polyisoprene LectureGeneral Introduction to Polymers. Reaction Types and Processes. Introduction to Step Growth. Polymer Design and Synthesis. Reaction Types and Processes. Covalent vs. The differences between the properties of crystalline organic materials of low molecular weight and the more indefinable class of materials referred to by Graham in as ‘colloids’ has long engaged the attention of chemists POLYMER CHEMISTRY Introduction to polymers: Nomenclature – Functionality. Introduction to Step Growth. Karen L. Wooley. How do polymeric crystals accommodate the polymer chain? Need to use statistical properties to describe ChapterISSUES TO ADDRESS What are the basic microstructural features? Polymer Design and Synthesis. (PDF) Step Growth PolymerizationMolecular Weight Mod Lec Introduction to Polymers. Atactic polymer: It is a polymer with the random orientation of the substituents with respect to the main chain of the polymer. Polymers and polymerizations. The macromolecules are bonded together by weak Van der Waals LecturePolymers IIntroduction. Explain how polymer structure determines material properties, Lecture Notes: Introduction To Polymer Chemistry. Describe a polymer’s structure in terms of –mer type ordering, tacticity, and backbone chain configuration. (PDF) Step Growth PolymerizationMolecular Weight (MW) Control.
