Abstract: 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.

Abstract: 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.
