Abstract: An elastosol is provided by combining a finely powdered, linear or branched block copolymer of a monovinyl aromatic compound and a conjugated diene having a particle size of 800 micron or less, and a rubber compatible liquid plasticizer, wherein the weight ratio of the block copolymer to the plasticizer is in the range of from 0.1 to 10. Furthermore, there is provided a process for the preparation of an elastosol as well as a process for the preparation of a homogeneous rubbery product derived from said elastosol.

Abstract: The present invention relates to a mixture of polyols for use in the preparation of polyurethane foam comprising:(i) 80-99% by weight of at least one polyether polyol and/or at least one polyester polyol; and(ii) 1-20% by weight of at least one polyolefin polyol.The invention further relates to a process for preparing polyurethane foams, using the said mixture of polyols; to polyurethane foams obtainable by such process; and to articles and composites containing the said polyurethane foams.

Abstract: Intermediate binder composition for use in toner compositions, comprising (a) a block copolymer comprising one predominantly poly(monovinyl aromatic) block per molecule and one predominantly poly(conjugated diene) block per molecule, the latter blocks being selectively hydrogenated to a residual unsaturation degree of 20% or lower, in an amount of from 5 to 35% by weight relative to the weight of the intermediate binder composition, and a microcrystalline wax, having a weight average molecular weight of from 1000 to 10,000, and having a drop point of 75.degree. C. or higher (measured according to ASTM D 3104), in an amount of from 95 to 65% by weight relative to the weight of the binder composition. Also covered are electrophotographic toner compositions containing the intermediate binder composition and magnetizable particles.
