a) HCl a. III. We have step-by-step solutions for your textbooks written by Bartleby experts! b) [─O─R─CO─]n Characteristics of Addition Polymerization n Many monomers bond together via rearrangement of bonds n There is no loss of atoms or molecules when monomers bind n Most of the common addition polymers are formed from unsaturated monomers (usually having a double bond) n Addition polymers are generally chemically inert. View Answer, 10. The repeating units represent monomers. This condensation can form what are known as multimers or polymers. Characteristics of addition polymerization: 1) Monomers activate one at a time 2) Monomers add *in seq ... Another name for condensation polymerization is _____ polymerization. Common condensation polymers include polyamides, polyacetals, and proteins. High coefficient of friction c. Low density d. ... Condensation polymerization. The terminal functional groups on a chain remain active, so that groups of shorter chains combine into longer chains in the late stages of polymerization. • Polymers can be classified into 2 types as per their preparation process they undergo – Addition polymerization and Condensation Polymerization. What is the product of following polymerization reaction? They have a very high melting point. Request full-text PDF. The terminal functional groups on a chain remain active, so that groups of shorter chains combine into longer chains in the late stages of polymerization. The terminal functional groups on a chain remain active, so that groups of shorter chains combine into longer chains in the late stages of polymerization. Condensation polymerization "Step growth polymerization" and condensation polymerization are two different concepts, not always identical. condensation) versus Chain-Growth (e.g. Addition Polymerization Condensation Polymerization There are two types of polymers: Natural polymers : They are those found in nature. 4. c) 2n-1 For example, when ethylene is polymerized to make polyethene, every atom (present in the monomer) of ethylene becomes a part of the polymer. Click here to navigate to parent product. Pages 160. eBook ISBN 9781315155876. Which of the following does not result in the formation of an ester? Chain-reaction polymerizations are three way operations that involve two structures, including the aforementioned monomers as well as free radical catalysts. 2.2. free radical) Polymerization; Step-Growth: Chain-Growth: All molecules present (monomer, oligomer, polymer) can react with any other molecule. d) none of the mentioned IV. In fact polyurethane polymerizes with addition polymerization (because its polymerization produces no small molecules), but its reaction mechanism corresponds to a step-growth polymerization. Loss of each kind of functional group in each step for bifunctional species 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. b) water Consider a reaction of polymer formation by condensation polymerization, completed in n-steps, with the liberation of a certain byproduct. DOI link for Characteristics of Polymers and Polymerization Processes. To practice all areas of Polymer Engineering, here is complete set of 1000+ Multiple Choice Questions and Answers.
