Patent number: 4458047Abstract: A novel process for making novel naphthalene hydrodimer mixtures which contain PTB in varying amounts and have improved plasticizing properties over PTB alone. The improved plasticizing composition is prepared by contacting a mixture of a hydronaphthalene (e.g., tetralin or an alkyltetralin) and naphthalene or an alkylnaphthalene with a strong acid catalyst. Another embodiment of the invention is the plasticized composition.Type: GrantFiled: June 7, 1982Date of Patent: July 3, 1984Assignee: Sun Tech, Inc.Inventor: William D. Vanderwerff
