DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) The first order rate const. and the total activation energy in the polymn. of 1,3-butadiene [106-99-0] with propylene [115-07-1] using a catalyst composed of neopentanol [75-84-3], VOCl3, and Al(iso-Bu)3 [100-99-2] at -20 to -80° were obtained. The polymn. rate was first order dependent on monomer and catalyst concn. The optimum polymn. temp. was -50 to -60°. .

DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Isobaric heat capacities Cp in the liq. phase of seven isomeric C5 alkanols and in the solid phase for 2,2-dimethyl-1-propanol were measured by a com. 75-85-4 and 598-75-4 are also in the experiment. SETARAM heat conduction calorimeter. Results obtained cover the following temp. range: 2-methyl-1-butanol (CAS-RN 137-32-6) 308-338 K, 2-methyl-2-butanol (75-85-4) 308-348 K, 3-methyl-1-butanol (123-51-3) 308-357 K, 3-methyl-2-butanol (598-75-4) 304-347 K, 2-pentanol (6032-29-7) 308-367 K, 3-pentanol (584-02-1) 308-368 K, 2,2-dimethyl-1-propanol (75-84-3) 310-363 K. The heat capacity data obtained in this work were merged with available exptl. data from literature, critically assessed, and sets of recommended data were developed by correlating selected data as a function of temp. .
