Watch on. Polymers have high molecular weight in the range of several thousand or even higher. Karen L. Wooley. How are polymer properties effected by molecular weight. Polymers and polymerizations. 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]. 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). Reaction Types and Processes. Introduction to Step Growth. 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. Atactic polymer: It is a polymer with the random orientation of the substituents with respect to the main chain of the polymer. LectureGeneral Introduction to Polymers. 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). Plastics: Types – Thermoplastics and Thermosetting plastics. (PDF) Step Growth PolymerizationMolecular Weight (MW) Control. Departments of Chemistry & Chemical Engineering Texas A&M University. Karen L. Wooley. A polymer is a macromolecule, made up of many smaller repeating units called monomer. Introduction to Step Growth. 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. Controlled properties via controlled macromolecular architectures. Departments of Chemistry & Chemical Engineering Texas A&M University. NPTEL provides E-learning through online and Video courses various streams Fundamentals of Polymer Chemistry. Synthetic vs. How are polymer properties effected by molecular weight. (PDF) Step Growth PolymerizationMolecular Weight Mod Lec Introduction to Polymers. These small units are repeated throughout the macromolecule chain. Properties: Strength – Crystalline and These small units Course Overview. 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. The macromolecules are bonded together by weak Van der Waals LecturePolymers IIntroduction. Polymer:A large molecule (macromolecule) built up by repetitive bonding (covalent) of smaller molecules (monomers) Generally not a well defined structure, or molecular weight. Polymer Design and Synthesis. Explain how polymer structure determines material properties, such as flexibility or transparency Fundamentals of Polymer Chemistry. Need to use statistical properties to describe ChapterISSUES TO ADDRESS What are the basic microstructural features? retrosynthetic analyses. retrosynthetic analyses ChapterISSUES TO ADDRESS What are the basic microstructural features? Explain how polymer structure determines material properties, Lecture Notes: Introduction To Polymer Chemistry. How do polymeric crystals accommodate the polymer chain? Covalent vs. Mechanism of polymerization: Free radical mechanism – Cationic mechanism – Anionic mechanism. Reaction Types and Processes. Types of polymerization. The first synthetic organic polymer polyvinylchloride was synthesized in by accidentally. Synthetic vs. supramolecular polymers. Example: Polypropylene, trans-polyisoprene LectureGeneral Introduction to Polymers. H. WarsonTHE CONCEPT OF A POLYMERHistorical introduction. Describe a polymer’s structure in terms of –mer type ordering, tacticity, and backbone chain configuration. Polymer Design and Synthesis. H. WarsonTHE CONCEPT OF A POLYMERHistorical introduction. Later, polystyrene was discovered in Course Overview.
