However, polymer processing applications
Polymerization considering the mechanism of the reaction and chemical structure of the polymer. Then, the findings indicated Polymer profit sector applications into four categories, as detailed below polymer profit sector steep step or condensation polymerization profit sector steep chain radical or added to the polymer earnings. Access application form ionic polymer processing applications was a co op di Taser one. However, application of polymer processing step or condensation (Condensation Polymerization or Step) 1.1. Polymer profit sector steep stepwise linear (Linear Step Polymerization) to prepare the polymer type, the number of functional terminal (functional) are very important, for example, the preparation of charters. The interactions among carboxylic Malik and hydroxyl groups in a molecule of acetic acid and ethanol, both of which are among the functional molecules only among single. (Monofunctional compounds) is a product of the reaction, ethyl acetate and water equation , but because the two reactants are among only a single functional group. Ethyl acetate thus formed no functional groups that can react to a late polymer is considering the reaction of phthalic acid Theresa Park. (Terephthalic acid) and ethylene glycol (ethylene glycol), both of which molecules have functional terminal 2 groups (difunctional compounds) esters at the end of the acidic carboxyl acrylic. Reacting to the end of a hydroxyl called Mercury (dimer) which alumni can react to a tri-polymer (trimer) or tetrachloride Mercury (tetramer) are among. Functional Category 2 (difunctional tetramer) and reactions continue to have a high molecular weight polymer with a linear structure. If the monomer, which are among the nationalists over two pig will polymer with branches like an acid Theresa May metallic react with glycerol (glycerol: HOCHB2BCH (. OH) CHB2BOH), which is among the three functional categories of products will be a polyethylene thermoplastic that is not a straight line , 1.1.1. Poly Polycondensation (Polycondensation) reaction of a small molecule is eliminated during the reaction as a molecule of water is eliminated during the preparation of polyethylene thermoplastic linear. The equation below when R1 and R2 represent a hydrocarbon addition, poly esters can also be prepared from the monomer-type single-functional two categories such as (- hydroxy carboxylic acids) , poly amide. there can be prepared from condensation reaction between the monomer's functional groups, with two groups like amines and carboxylic in Addis version 1.1.2 poly (Polyaddition) is a polymer, however, the application process. monomer's functional groups with two groups but not eliminate small molecule during the reaction. For example, poly urethane. (Polyurethanane) prepared from the reaction between isobutane cyanate. (Diisoscyanate) and diol (diol) poly-urea (polyurea) is the reaction of the iso cyanate. (Diisocyanates) with the amines (diamines) bringing the reaction Diels-Alder was used to prepare the polymer as a polymer's staggering collection of cyclo - propane Ta diene (cyclopentadiene) equation. 1.2 polymer-profit sector steep step that is not a straight line (Non-Linear Step Polymerization) is a reaction between the monomer, which are among the nationalists over two among the first to get the structure of the polymer. which has branches And after that, there will be increasing the size or weight quickly. And finally to have polymer cross-linking structure. Which have properties different from the linear polymer. For example The reaction between the carboxylic acid Malik (dicarboxylic acid: R (COOH) 2) and tri Montreal (triol: RP'P (OH) 3) which is among the three groups have functional polymer. reticular structure as a polymer cross-linking structure (Network Polymers) polymer of formaldehyde. (Formaldehyde-based resins), a polymer cross-linking a first polymer was prepared by step application process and is used commercially. Start by preparing a polymer with a low molecular weight. The polymer can be made to flow under pressure and heat in a mold (mold) for forming a polymer cross-linking structure and are shaped by the mold. Because formaldehyde has two functional groups are among the causes of reticular structure must substrates. (Coreactants) with a number of functional groups. (Functionality, f) over two among the most common use of phenol (f = 3) Urea (f = 4) and melamine (F = 6) Formaldehyde Phenol Urea Melamine.
