Free Radical Vinyl Polymerization Of Teflon

Free radical polymerization can be iniitated by thermal chemical or photolytic decomposition of initiator molecules.

Free radical vinyl polymerization of teflon.

Tetrafluoroethylene monomer nc f 2 c f 2. Teflon is synthesized using a free radical addition or chain growth polymerization technique. The plastics that have so changed society and the natural and synthetic fibres used in clothing are polymers. Addition polymers namely polythene teflon and polyacrylonitrile are formed by a free radical mechanism of addition polymerization.

Chemical reaction chemical reaction polymerization reactions. Following its generation the free radical then reacts with a vinyl monomer that is it adds to one of the electrons of the double bond of the vinyl monomer and the remaining electron becomes the new free radical. Free radical polymerization is a type of chain growth polymerization where the polymer is formed by consecutive addition of unsaturated monomer molecules to an active free radical center. The same steps are followed in the polymerization of other substituted alkenes.

Free radical and raft polymerization of vinyl esters with different molecular dimensions are conducted in the nanochannels of metal organic frameworks mofs. Free radicals can be formed by a number of different mechanisms usually involving separate initiator molecules. A linking small molecules together a type of addition. Steps in the free radical polymerization of vinyl chloride.

Free radical polymerization frp is a method of polymerization by which a polymer forms by the successive addition of free radical building blocks. R m rm. Chemical characteristics of teflon chemically teflon belongs to the class of paraffin polymers. So we are describing here the free radical mechanism of addition polymerization.

Terylene melamine polymer and nylon 6 6 are synthesized using condensation step growth polymerization technique. There are two basic ways to form polymers. Teflon is produced from free radical vinyl polymerization of tetraflouroethylene resulting in the formation of polytetraflouroethylene or teflon. Free radical polymerization last updated save as pdf page id 35129 radical chain growth polymerization contributors all the monomers from which addition polymers are made are alkenes or functionally substituted alkenes.

However in this paraffin fluorine atoms replace all the hydrogen atoms. Simple alkenes are the source of many common plastics. Polymers are high molecular weight compounds fashioned by the aggregation of many smaller molecules called monomers.
