Polychlorotrifluoroethylene structure

The family of FPs, also called fluorocarbon plastics, is based on polymers made of monomers composed of fluorine and carbon may also include chlorine atoms in their structure. Specific types include polytetrafluoroethylene (PTFE), polytetrafluoroethylene-cohexafluoro-propylene or fluorinated ethylene propylene (FEP), polytrafluoroethylene-coperfluoropropylvinyl ether (PFA), ethylenetetrafluoroethylene (ETFE). polychlorotrifluoroethylene (PCTFE), ethylene-chlorotri-fluoroethylene (ECTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), perfluoromethylvinylether (PFMV), perfluoroalkoxy (PFA), etc. 

Oxygen (0) and chlorine (Cl) are present in the chemical structure of some commercial fluoropolymers. Examples include perfluoroalkoxy polymer and polychlorotrifluoroethylene ... 

More recently, calculation of the LCST for polyethylene, polyvinylidene chloride, polychlorotrifluoroethylene, polystyrene, and polypropylene was undertaken using a theoretical method of atom connectivities for polymer and solvent (Liu and Zhong, 2005) (see Table 1.1.1). Some solvents of choice were water, butane, acetone, toluene, cyclopentane, t-butanol and methyl ethyl ketone, and THF The LCST values for polyethylene, polyvinylidene chloride (PVDC), and polychlorotrifluoroethylene with the solvents are the same, because of the structure connectivity rules.

PTFE molecules have little propensity for polarization or ionization, which minimizes the nonpolar energy or foree between PTFE molecules and between PTFE and other molecules. There are also no permanent dipoles in its structure, which is not the ease for polymers such as polychlorotrifluoroethylene and... 

Polychlorotrifluoroethylene (PCTFE or CTFE) is a homopolymer of chlorotrifluoroethylene, characterized by the structure shown in Fig. 11.38.
