Abstract
Phenyltetralylbutane (PTB) is used to plasticize polyvinylchloride (PVC) resins. The PTB in one embodiment is prepared by refluxing tetralin an flowing condensed vapors of the tetralin over a bed of strongly acidic catalyst, which may for example be a synthetic acid "Y" type zeolite. In one embodiment, the PTB is used as a secondary plasticizer, with a primary plasticizer such as di(2-ethyl)hexyl phthalate.
