Patent number: 4260538Abstract: This invention relates to an improved, matured, moldabe, thermosetting polyester resin system which includes at least two different polyester resins, one of which is faster reactive and containing a minor amount of isophthalic acid and the other of which is slower reactive and devoid of such acid, such system also including suitabe reinforcing fibers and inert filler along with an organic polyisocyanate, a metallic oxide or hydroxide, an aliphatically-unsaturated monomer, a free radical polymerization catalyst, and an internal mold release agent, the resin system being especially useful for pressure molding of precisely-formed articles having greatly improved impact resistance and flexibility.Type: GrantFiled: September 27, 1979Date of Patent: April 7, 1981Assignee: The Budd CompanyInventors: Kenneth A. Iseler, Mayur S. Shah

Patent number: 4259198Abstract: The invention relates to the use of crystalline resins as storage material in latent heat accumulators. Crystalline synthetic resins replace the crystalline inorganic salt of the known latent heat reservoirs. Preferably epoxide resins, polyurethane resins and polyester resins, which contain very specific long-chain polyester molecule moieties, are used. The crystalline synthetic resins have one or more, preferably two, crystallite melt temperatures.Type: GrantFiled: November 28, 1978Date of Patent: March 31, 1981Assignee: Ciba-Geigy CorporationInventors: Ursula Kreibich, Rolf Schmid
