I. Compounds.
1. In the names of substances which are polymers of compounds containing a vinylidene group C=CH2.
a. polyvinylidene chloride n. any of a class of resinous polymers of vinylidene chloride in which the repeating unit is the group —CH2—CCl2—, and which have a wide range of applications, esp. as impact- and chemical-resistant films and fibres; abbreviated PVDC.
