The numbers preceding the poly prefix designate the first and last carbon atoms of the backbone repeating unit. Only I b. Polytetrafluoroethylene (Teflon) has a repeat unit with the formula F2C—CF2 . It is similar to polytetrafluoroethene (PTFE), except that it is a homopolymer of the monomer chlorotrifluoroethylene (CTFE) instead of tetrafluoroethene. Polychlorotrifluoroethylene (PCTFE or PTFCE) is a thermoplastic chlorofluoropolymer with the molecular formula (CF 2 CClF) n, where n is the number of monomer units in the polymer molecule. A sample of the polymer consists of fractions with the following distribution of chains: (a) Determine the molar mass of each fraction. Answer Save. 1 decade ago. I. polypropylene II. Concept Introduction: Teflon is an addition polymer of tetrafluoroethylene. Anonymous. Previous Question Next Question. Teflon is chemically inert, has high melting temperature of 372 degree celcius & has low coefficient of Friction. The structural formula of monomer and basic repeating unit of the polymer teflon should be drawn. Relevance. a. polyethylene b. polyvinyl chloride c. Teflon d. polypropylene e. polystyrene. 1 Answer. Teflon is polytetrafluoroethylene, or PTFE. The repeating unit or monomer of teflon is CF = CF. Teflon: Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Teflon is used for non-stick coating of pans and other cookwares . Which of the following is (are) condensation polymer(s)? Expert Solution. How are polymers classified on the basis of structure? For polyethylene, arguably the simplest polymer, this is demonstrated by the following equation. This is the basic repeating unit (chain link) or "monomer" in the polymer PTFE. We can represent the addition polymerisation reaction of tetrafluoroethene in a number of different, but equivalent, ways: 1601 Views . i) H H ii) H H C = C C – C H H H H iii) H CH 3 iv) Cl H C C C – C ... Write down the repeating unit of polythene ii) Write down the formula for the monomer polythene. How was it discovered? Draw the structure of the monomer and the basic repeating unit for each of the following polymeric substances. Glass Transition Temperatures of Amorphous Polymers.
