The mixture of said components is heated to a temperature within the range of from 130.degree. to 200.degree. C., whereupon the desired product is formed. The process may be conducted in the presence of a catalyst comprising a mixture of tin dichloride and hexamethylene diamine.The resulting powder-like furna resin is resistant against highly-aggressive media at a temperature of up to 120.degree. C.; it is also resistant against the effect of oxidizing agents at a temperature of up to 80.degree. C. Martens yield temperature of the powder-like furna resin of the present invention is as high as 300.degree. C. The resin yield is as high as 93%.Type: GrantFiled: June 26, 1978Date of Patent: February 5, 1980Inventors: Ildgam A. Bekbulatov, Juldash Mamatov, Gennady D. Varlamov, Shavkat Madaliev, Valery M.

Patent number: 4187369Abstract: The process according to the present invention comprises a continuous polycondensation of the anthracene fraction of coal tar boiling within the range of from 270.degree. C. to 350.degree. C., phenol and formaldehyde at a weight ratio between the components of 1:3-4:1-1.2 in the presence of 0.5 to 1.2% by weight of an acidic catalyst at a supply rate of a mixture of said components of 500-550 g/hr.The present invention makes it possible to continuously prepare the desired product, whereby its output from a unit production volume is substantially increased. The product has a high curing rate and a high coke value.Type: GrantFiled: September 6, 1978Date of Patent: February 5, 1980Inventors: Rudolf Z. Pavlikov, Natalya V. Shorygina, Vladimir A. Strupinsky, Anatoly A. Kruglikov, Jury G. Farbshtein, Iosif L. Klipinitser

Patent number: 4187370Abstract: An alkaline-catalyzed process for preparing poly-2-pyrrolidone characterized by the step of treating the polypyrrolidone reaction product mixture with an acid to prevent polymer agglomeration and prevent base-catalyzed polymer degradation. In another embodiment, unreacted poly-2-pyrrolidone is recovered by washing the acid-treated polymer reaction product mixture with water and the resulting wash water recovered, treated with further acid, and then subjected to a two-stage evaporation process. Poly-2-pyrrolidone is known as nylon 4, and can be shaped into filaments and various molded articles.Type: GrantFiled: October 17, 1977Date of Patent: February 5, 1980Assignee: Chevron Research CompanyInventors: Byron E. Anshus, Kiyoshi Katsumoto, Ira M. Serkes

Patent number: 4187371Abstract: Terephthalic acid and either 5-methyl-1,9-nonanediamine or an isomeric mixture of 5-methyl-1,9-nonanediamine with 2,4-dimethyl-1,8-octanediamine and/or 2,4,6-trimethyl-1,7-heptanediamine are admixed in a methanol/water medium, wherein the volume ratio of methanol to water is in the range of about 99:1 to about 80:20, and the weight ratio of terephthalic acid and diamine to the methanol/water medium is in the range of about 1:1 to about 1:3. The resulting slurry can be cooled to promote precipitation of the salt. The precipitated salt can be recovered by filtration and employed for the production of a polyamide.Type: GrantFiled: August 8, 1975Date of Patent: February 5, 1980Assignee: Phillips Petroleum CompanyInventor: Robert W.
