A significantly improved plasticizer-polymer composition embraces a polymer containing a di-, tri- and/or tetra-ethyl-, propyl- and/or butylbiphenyl plasticizer which constitutes the major proportion by weight of any other plasticizing/softening additive, provided that the polymer is not polyvinyl chloride and when the polymer is an elastomer or rubber, or is a polystyrene, said plasticizer is diisopropylbiphenyl and/or triisopropylbiphenyl, and when the polymer is of a plastisol, essentially no ester plasticizing additive is present. As well, a polymer fabrication composition comprises a monomer and/or oligomer component in combination with said plasticizer. A method for preparing the plasticizer-polymer composition and/or the fabrication composition comprises contacting the monomer and/or oligomer component with said plasticizer, mixing to provide a uniform mixture, and carrying out further processing as may be desired so as to optionally prepare the plasticized-polymer composition. For instance, thermosets such as epoxies and polyurethanes and elastomers such as polybutadienes and other polymers can have high loading levels of the plasticizer employed without sacrifice of plasticized polymer properties. Moreover, the high loading capacity in many cases can represent a significant increase over that found from prior art plasticizing/softening additives.

A carbonless paper solvent is provided comprising diisopropylmethylnaphthalene, generally in an amount of from 20% to 100% of the total weight of the solvent. The solvent is combined with a chromogenic substance and is encapsuled into microcapsules. The microcapsules are applied to a sheet of material and a color developing substance is then applied to another sheet to form a carbonless marking system. When the microcapsules are ruptured, the solubilized chromogenic substance contacts and reacts with the developer to form an image. In a method of the invention, a by-product fraction consisting of components with a boiling point range of 200.degree. to 400.degree. C. are contacted with propylene under conditions sufficient to form an alkylation product comprising diisopropylmethylnaphthalene.

A remarkably low odor carbonless paper solvent is provided comprising a mixture of diisopropylbiphenyl and triisopropylbiphenyl, generally in an amount of 50 to 90% by weight diisopropylbiphenyl and 10 to 40% by weight triisopropylbiphenyl. The solvent and a chromogenic substance such as a leuco dye are encapsulated to form microcapsules which are coated onto one surface of a carrier sheet. A color developing substance is then applied to another sheet to form a carbonless marking system. When the microcapsules are ruptured, the solubilized chromogenic substance contacts and reacts with the developer to form an image.

A water-white, essentially odorless liquid useful as a dieletric oil and as a dye solvent, particularly for a carbonless paper solvent, consisting essentially of about 82% to about 88% by weight of mono-sec-butylbiphenyl and about 12% to about 18% of di-sec-butylbiphenyl prepared by reacting highly pure 1-butene or 2-butene with biphenyl at a mol ratio of butene to biphenyl of from about 0.5 to about 0.9 and at a temperature of about 250.degree. F. to about 475.degree. F. in the presence of an aluminum chloride catalyst, distilling the reaction product under vacuum to remove unreacted biphenyl and distilling off the product mixture at a temperature between about 370.degree. F. and about 440.degree. F. at 30 mm Hg. pressure or the equivalent thereof.
