Vinylidene group - Wikipedia
In chemistry, vinylidenes are compounds with the functional group C=CH 2. An example is 1,1-dichloroethene (CCl 2 =CH 2) commonly called vinylidene chloride. It and vinylidene fluoride are precursors to commercially useful polymers.
1,1-Dichloroethylene - Wikipedia
1,1-Dichloroethylene, commonly called vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula CCl2CH2. It is a colorless liquid with a sharp odor.
Polyvinylidene fluoride - Wikipedia
Polyvinylidene fluoride or polyvinylidene difluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Its chemical formula is (C 2 H 2 F 2) n. PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids and hydrocarbons.
