Poly propene repeating unit
WebDec 7, 2024 · Since polymers are made by linking together many identical small molecules, there are repeating units in polymers. Here’s an example, polyvinyl chloride, in which the repeating unit is -CH2-CHCl-. In poly (vinyl chloride) the repeating unit comes directly from the end-to-end linking of many vinyl chloride molecules.

WebSilicones are synthetic polymers with a silicon-oxygen backbone similar to that in silicon dioxide (silica), but with organic groups attached to the silicon atoms by C-Si bonds. The silicone chain exposes organic groups to the outside. Thus, despite having a very polar chain, the physical properties of silicones are similar to those of an alkane. WebPolychlorotrifluoroethylene (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. It is similar to polytetrafluoroethene (PTFE), except that it is a homopolymer of the monomer chlorotrifluoroethylene (CTFE) instead of tetrafluoroethene. It has the lowest …
