Polyvinyl chloride (PVC) homopolymer is a semi-crystalline polymer with a relatively high room temperature tensile modulus of 2400 to 4140 MPa (3.5–6.0 · 105 psi), depending on formulation) that can be lowered by plasticizing entities to produce semi-rigid and flexible items. Many of these have turned out to be commercially useful and cost competitive. Use of other additives, in addition to plasticizers, is essential to making successful flexible PVC products. These include stabilizers, pigments, fillers, lubricants, and many specialty additives such as fire retardants, anti-microbials, UV-screeners, and antistats for particular applications.
To put the development of flexible PVC in perspective, some historical facts are of interest. Of the seminal discoveries leading to successful flexible PVC products, some were empirical and others the results of classical theory-driven research. Space allows only a few of these milestones to be described here.
In Germany prior to World War I, the development of electric lighting resulted in a large excess of calcium carbide as acetylene lamps were phased out. Fritz Klatte, working for
Chemische Fabrik Griesheim-Elektron, found that acetylene can react with HCl to form vinyl chloride monomer (VCM), which in turn, can be polymerized to PVC using free-radical initiators. Klatte was then commissioned to find uses for the hard, horny intractable PVC resin. He
