types of polymerization

A polymer is a large molecule that is made up of repeating subunits connected to each other by chemical bonds.Do you need some examples of polymers? Here is a list of materials that are natural and synthetic polymers, plus some examples of materials that are not polymers at all. Compute the following: A) What is the number-average molecular weight? to give Nylon – 66, where molecules of water are eliminated in the process. In this lesson, learn about the process of polymerization. IUPAC definition Polymerization: The process of converting a monomer or a mixture of monomers into a polymer. How are these monomers put together?

What is the International Baccalaureate Middle Years Program? Polyester and nylon are some of the most common examples of this type. Addition Polymerization ; 3. There are two types of polymerization known as step-reaction polymerization or condensation and chain-reaction polymerization. In polymer chemistry, polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. In addition polymerization, monomers react to form a polymer without the formation of by-products. Here is a list of materials that are natural and synthetic polymers, plus some examples of materials that are not polymers at all. Hence the technique is also known as Pearl polymerization / Granular polymerization / Bead polymerization. But the alphabet-word building analogy actually falls well short because most words are not very long. The ion produced in this reaction adds monomers to produce a growing polymer chain. The polymerization takes place inside the droplet & product formed being insoluble in water. © copyright 2003-2020 Study.com. credit by exam that is accepted by over 1,500 colleges and universities. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons • In condensation polymerization, a small portion of the monomer molecule is not incorporated in the final polymer. The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water. Initiation, propagation and finally termination. Cloudflare Ray ID: 6065d5799fe073ad Polymerization: The process of converting a monomer or a mixture of monomers into a polymer..

Which of the following will give a polymer when condensed with adipic acid: (a) ethanol, (b) ethylene glycol, (c) glycerol, (d) aniline, or (e) ethylenediamine?
