Free Radical Vinyl Polymerization Of Teflon

Chemical characteristics of teflon chemically teflon belongs to the class of paraffin polymers.

Free radical vinyl polymerization of teflon.

Free radical polymerization frp is a method of polymerization by which a polymer forms by the successive addition of free radical building blocks. So we are describing here the free radical mechanism of addition polymerization. Polymers are high molecular weight compounds fashioned by the aggregation of many smaller molecules called monomers. R m rm.

Free radical polymerization can be iniitated by thermal chemical or photolytic decomposition of initiator molecules. 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. Simple alkenes are the source of many common plastics. 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.

The same steps are followed in the polymerization of other substituted alkenes. Most commonly addition polymerization is governed by free radical formation. In table 3 1 the names structures and products formed in some polymerization reactions are listed. Addition polymers namely polythene teflon and polyacrylonitrile are formed by a free radical mechanism of addition polymerization.

Teflon is produced from free radical vinyl polymerization of tetraflouroethylene resulting in the formation of polytetraflouroethylene or teflon. Terylene melamine polymer and nylon 6 6 are synthesized using condensation step growth polymerization technique. There are two basic ways to form polymers. Steps in the free radical polymerization of vinyl chloride.

Teflon is synthesized using a free radical addition or chain growth polymerization technique. Chemical reaction chemical reaction polymerization reactions. The plastics that have so changed society and the natural and synthetic fibres used in clothing are polymers. A linking small molecules together a type of addition.

Free radical and raft polymerization of vinyl esters with different molecular dimensions are conducted in the nanochannels of metal organic frameworks mofs. Tetrafluoroethylene monomer nc f 2 c f 2. However in this paraffin fluorine atoms replace all the hydrogen atoms.
