91polymerizations — polymerization (Amer.) pÉ™ lɪmÉ™rÉ™ zeɪʃn / raɪ z n. combination of two or more separate molecules to form a more complex molecule (also polymerisation) …
92industrial polymers, chemistry of — Introduction structure and composition of chemical compounds made up of long, chainlike molecules (molecule). What distinguishes polymers from other types of compounds is the extremely large size of the molecules. The size of a… …
93industrial polymers, major — Introduction chemical compounds used in the manufacture of synthetic industrial materials. In the commercial production of plastics, elastomers, man made fibres, adhesives, and surface coatings, a tremendous variety of polymers are… …
94Chain growth polymerisation — Chain growth polymerization is a polymerization technique where unsaturated monomer molecules add on to a growing polymer chain one at a time [1]. It can be represented with the chemical equation: where n is the …
95Polythiophene — The monomer repeat unit of unsubstituted polythiophene …
96Polymer — Appearance of real linear polymer chains as recorded using an atomic force microscope on surface under liquid medium. Chain contour length for this polymer is 204 nm; thickness is 0.4 nm.[1] A polymer is a large molecule (macromolecule …
97Chain transfer — is a polymerization reaction by which the activity of a growing polymer chain is transferred to another molecule.[1][2] P• + XR → PX + R • Chain transfer reactions reduce the average molecular weight of the final polymer. Chain transfer can be… …
98hydrocarbon — hydrocarbonaceous, adj. /huy dreuh kahr beuhn, huy dreuh kahr /, n. any of a class of compounds containing only hydrogen and carbon, as an alkane, methane, CH4, an alkene, ethylene, C2H4, an alkyne, acetylene, C2H2, or an aromatic compound,… …
99Ziegler–Natta catalyst — A Ziegler–Natta catalyst is a catalyst used in the synthesis of polymers of 1 alkenes (α olefins). Three types of Ziegler–Natta catalysts are currently employed: Solid and supported catalysts based on titanium compounds. They are used in… …
100Olefin metathesis — or transalkylidenation is an organic reaction that entails redistribution of alkylene fragments by the scission of carbon carbon double bonds in olefins (alkenes).[1] Its advantages include the creation of fewer sideproducts and hazardous wastes …
