Examples – Rayon (cellulose acetate), cellulose nitrate, etc. Alessandro Gandini. use as they can be melt-processed more readily than poly(tetra-fluoroethylene). Another type of polymers is formed by conducting a condensation reaction. The aliphatic polyamides are, commonly called nylons. During the polymerization process, the double bonds in the alkenes break and they all join together to form a large molecule. It is used in speciality packaging, orthopaedic devices and in controlled release of drugs. Polyvinyl chloride (PVC) is a plastic polymer made of monomer vinyl chloride. Download Identifying Monomers In Polymers Worksheet doc. Here ethylene (ethene) is the monomer, and the corresponding linear polymer is called high-density polyethylene (HDPE). Most important addition polymers are polymerized from olefins and vinyl-based monomers. These materials tend to be thermally stable and are used in high temperature applications. CHAPTER 5: STRUCTURE OF POLYMERS "The time has come," the Walrus said, "To talk of many things: Of shoes--and ships--and sealing-wax-- Of cabbages--and kings--" Lewis Carroll, Through the Looking Glass (1872) shoes, ship, sealing wax, cabbage, and a king The "many things" listed by the Walrus are actually very similar in chemical composition and structure. Learning Outcomes: • You should be able to: • List examples of natural polymers and their monomers, • Draw the structural formula of natural rubber, • Polymer is made up of macromolecules which contain repetitive small unit (monomer) in a long chain.

It is used as a substitute for wool in making commercial fibres such as orlon or acrilan. Examples – Teflon, Nylon 6,6 , Synthetic rubber (Buna – S) etc. c). Monomers are the building blocks of more complex molecules, called polymers. Step 3: Chain terminating step: For termination of the long chain, free radicals combine in different ways to form polythene. Synthetic polymers are produced in different types of reactions. For monomers to bond together a chemical reaction occurs, this is a condensation reaction. A molecule is nothing but a group of two or more atoms held together by chemical bonds. While many people use the term 'polymer' and 'plastic' interchangeably, polymers are a much larger class of molecules which includes plastics, plus many other materials, such as cellulose, amber, and natural rubber. Polymers: Polymers are high molecular mass substance consisting of large number of repeating structural units. To qualify as an oligomer, the properties of the molecule need to change significantly if one or a few subunits are added or removed. The majority of polymers in this category consist of vinyl acetate and its copolymers. Fibres are the thread forming solids which possess high tensile strength and high modulus. Poly(vinylidenechloride) copolymers have self-adhesive (clinging) characteristics. The urea-formaldehyde resin is a non-transparent plastic obtained by heating formaldehyde and urea.

Polyethylene is considered to be as one of the simplest polymer, it has ethene or ethylene as the monomer unit whereas the linear polymer is known as the high density polyethylene-HDPE. n [Monomer] → Polymer Difference between Polymers and Macromolecules Polymers are also called macromolecules due to their large size but converse is not always true. Polysciences stocks a wide portfolio of monomers and polymers and specializes in custom synthetic capabilities. The physical and chemical properties of polymers vary widely, based on their monomers, structures, and additives. Polystyrene film is highly transparent to visible radiation and has a high, Poly(vinyl acetal)s are prepared by reacting aldehydes with poly(vinyl alcohol), which is made by hydrolyzing poly(vinyl, acetate). monomers are converted to low molecular weight species, such as dimers, trimers, tetramers, etc. Phenol – formaldehyde polymer (Bakelite and related polymers). A polymer may be a natural or synthetic macromolecule comprised of repeating units of a smaller molecule (monomers). Poly(vinyl acetate) is unique in that the, most common polymerization method results in a nonlinear, highly branched polymer. Polysciences stocks a wide portfolio of monomers and polymers and specializes in custom synthetic capabilities. If we consider only wooden ships, then all of the things on the list are composed of large carbon frameworks called polymers. Polymers are long chain, giant organic molecules are assembled from many smaller molecules called monomers.Polymers consist of many repeating monomer units in long chains, sometimes with branching or cross-linking between the chains. It is this feature of large size that gives polymers their special properties. Since, each step produces a distinct functionalized species and is independent of each other, this process is also called as step growth polymerisation. This non-toxic surface treatment can be applied by anyone in very little time and in a number of different ways to produce, lasting, highly uniform, hydrophobic water repelling barriers that water molecules simply cannot connect to, leaving it to bead. A variety of homo- and copolymers containing these monomers is available. They are commonly used in the preparation of, polyesters and polyurethanes. approach adopted then was to base the assessment of polymers on monomers, and therefore register monomers only.
