Abstract: A low density polymer composition including a polymer component capable of being cured, a low density filler in an amount sufficient to reduce the density of the polymer and a thixotrope present in a sufficient amount to impart a sufficient viscosity and to inhibit separation of the filler from the polymer until after the polymer is cured. The resulting lightweight, filled polymer composition is a strong electrical insulator, has low shrinkage, a low coefficient of thermal expansion, low cured density and a soft filler that does not harden the polymer. Methods of preparing and using the low density polymer compositions are also disclosed.

Abstract: A process for producing a cleaved product from castor oil, or derivatives thereof, by high temperature caustic oxidation reaction accomplished by combining at least one chemically inert heat transfer fluid, a catalyst, and an alkali in aqueous solution to form a first mixture wherein the diluent is present in an amount sufficient to reduce foaming and solidification of the mixture while increasing the yield and improving the purity and adding a ricinic compound to the first mixture to form a second mixture. The temperature of the second mixture is raised to a level sufficient to conduct pyrolysis, and the cleaved product produced thereby is recovered by adding an acid to the reaction mixture in an amount sufficient to acidify the reaction mixture down below a pH of about 6. The invention further relates to the reaction mixture used to produce the cleaved products.
