The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. Pure polyvinyl chloride is a white, brittle solid. It is insoluble in alcohol but slightly soluble in tetrahydrofuran. PVC was accidentally synthesized in 1872 by German chemist Eugen Baumann. The polymer appeared as a white solid inside a flask of vinyl chloride that had been left exposed to sunlight. The polymerization of VCM is started by compounds called initiators that are mixed into the droplets.
