which of the following is an example of polymerization?

In addition polymerization (sometimes called chain-growth polymerization), a chain reaction adds new monomer units to the growing polymer molecule one at a time through double or triple bonds in the monomer. polymerization of ethylene into polyethylene). tutorial example problem showing how to calculate degree of polymerization in a nylon 6,6 sample with an average molecular weight of 250,000g/mol The electrophilic reagents (epoxide, aziridine, CO 2 , etc.) Formula (I) is provided. Which of the following is an example of a molecular… The polymerization process takes place in three distinct steps: 1. CHEM 379 – W20 Polymers & Polymerization 5-1 5. Understand the Key Differences Between Thermoplastic and Thermosetting Plastic with detailed explanations and examples. In this, small monomer units joined to form a giant polymer. Get more information in the following paragraphs. Which of the following is an example of a physical property? The way side group polymers are arranged on a polymer chain. Give an examples of a free-radical polymerization reaction (e.g. In two cases, when the mobility of the polymer becomes extremely low—as occurs, for example, in a built polymer- How to Calculate Degree of Polymerization. b) Plastic bag, … which of the following is a medical application using polymers? Organic polymers are assembled from carbon-based subunits, and will be the focus of this section of the course. CH4 C6H1206 N306 C2H2 2. polymerization definition: 1. a chemical reaction in which many small molecules join to make a polymer 2. a chemical reaction…. Addition polymerization differs from condensation polymerization, which does co-generate a product, usually water. Polymerization is of two types, condensation polymerization and addition polymerization. In addition, please find two application examples for each polymer listed below. This process is similar to radical polymerization, as demonstrated by the following equations. Condensation Polymerization. Here are 100 most important Multiple choice questions and answers on Polymer and Polymerization for the entrance exams. Also, the polymerization reactions for Nylon 6 and Spandex do not proceed by elimination of water or other small molecules. A procatalyst for the polymerization of ethylene and optionally one or more alpha-olefins having the structure shown in formula (I) below. examples include the polymerization of methyl methacrylate and vinyl chloride. In this article, we are going to discuss condensation type of polymerization. The plastics that have so changed society and the natural and synthetic fibres used in clothing are polymers. 1 In the case of a condensation reaction, two monomers combine with the loss of a small molecule, usually an alcohol, a water or an acid molecule, whereas an addition reaction involves only the rearrangement of the electrons of a double bond to form a single bond with another molecule. Common examples of emulsions include egg yolk, butter, and mayonnaise. Ionic polymerization therefore tends to produce a more regular polymer, with less branching along the backbone, and more controlled tacticity. When these occur during polymerization, they hold the main chains of the polymer further apart, creating a softer, more ductile & easy flowing material. The following examples of condensation polymers are illustrative. For suspension polymerization, initiation, propagation, and termination take place inside the droplet. They are often described as macromolecules due to their size. 2) The concentration of “active species” is very low. Polymerization is the process of covalently bonding the smaller monomers into the polymer. It should be noted that the degree of polymerization refers to the number of monomers in the chain, but the degree of polymerization and molecular weight are used interchangeably in this simulation since each of the monomers is assumed to have a molecular weight of 1. 1) Melamine-formaldehyde resin 2) Bakelite 3) Polythene 4) Polyester 22. An example of a condensation homopolymer is 1) Bakelite 2) Melamine-formaldehyde resin 3) Alkyl resin 4) Perlon or Nylon-6 23. Thermoset plastics are frequently used for sealed products due to their resistance to deformation and are also among some of the most impact resistant plastics available. The polyisobutylene product is a soft rubbery solid, T g = _ 70º C, which is used for inner tubes. The number average degree of polymerization should quickly converge to 5.
