[EAN: 9781234545826], Neubuch, [PU: RareBooksClub], U.S. GOVERNMENT,SUBJECTS, This item is printed on demand. Paperback. 24 pages. Original publisher: Washington, DC : National Aeronautics and Space Administration, 1991 OCLC Number: (OCoLC)645463443 Subject: Heterocyclic chemistry. Excerpt: . . . LAR 14643-1-CU-12-PATENT APPLICATION reaction mixture was diluted with 25 ml DMAc ( 5. 7 solids w w ) after approximately 0. 75 hour. The viscous solution was precipitated in a water acetic acid ( 10 1 ) mixture, washed successively in hot water and methanol and dried at 110 C to provide a light brown polymer ( 2. 48 g, 73 5 yield ) with a Tg of 276 C. The inherent viscosity of a 0. 5 solution in DMAc at 25 C was 1. 99 dL g. Unoriented thin films cast from a DMAc solution gave tensile strength, tensile modulus, and elongation at 23 C of 19. 4 ksi, 598 ksi, and 13. 1 respectively. The resulting polymer had the following structural repeat unit: Ft 10 15 Example 4 Into a 100 ml three necked round bottom flask equipped with nitrogen inlet, thermometer, mechanical stirrer, and Dean Stark trap was placed 5, 5 -carbonyl-bis 2-( 4-hydroxyphenyl ) benzimidazole ( 2. 5651 g, 5. 7 mmol ), 4, 4 -2O difluordbenzophenone ( 1. 2537 g, 5. 7 mmol ), pulverized anhydrous potassium carbonate ( 2. 0686 g, 15. 0 mmol ), dry DMAc ( 18. 5 ml, 18 solids w w ) and toluene ( 45 ml ). The mixture was heated to 140 -150 C for 3. 5 hours and then heated to 155 -160 C. After 1. 75 hours the viscous reaction mixture was diluted with 18 ml DMAc ( 10 solids w w ) and stirring continued 25 at 155 -160 C. The viscous reaction mixture was diluted with 20 ml DMAc ( 6. 7 solids w w ) after 0. 25 hour. Stirring was continued for 0. 5 hour at 160 C and the reaction mixture was cooled. The viscous solution was precipitated in a water acetic acid ( 10 1 ) mixture, washed successively in hot water and methanol and dried at 110 C to provide a pale yellow polymer 30 ( 3. 03 g, 84 yield ) with no observable Tg by differential scanning This item ships from La Vergne,TN.<
