Title: Method of preparing butyl rubber
Inventor: SHCHERBAN GEORGIJ TROFIMOVICH
IPC: C08F210/12
Filed: 1994-02-22
Granted: 1997-11-20
Abstract: FIELD: manufacture of synthetic rubbers, more particularly butyl rubber. SUBSTANCE: process is carried out by copolymerization of blend comprising isobutylene and isoprene monomers and hydrocarbon solvent. Copolymerization is carried out in the presence of organoaluminium catalyst. Some blend (in amount of 10-50) based on its total amount is treated with dry alkali, mixed with untreated stream, and total amount is directed for copolymerization. Treatment with alkali makes it possible to stabilize pH value of the blend aqueous extract and thus to regulate polymerization process. On completion of copolymerization, aqueous degassing is performed, polymer is recovered, and the resulting rubber is dried. The claimed method comprises treating hydrocarbon condensate distilled off during rubber degassing. Condensate is treated with aqueous alkali solution resulting from treatment of some hydrocarbon blend. EFFECT: more efficient manufacturing method. 1 dwg , 1 tbl

Abstract: FIELD: technical physical, thermophysical measurements. SUBSTANCE: in compliance with proposed method of determination of heat capacity and relaxation time of temperature field in capillary-porous materials surface of examined sample is exposed to action of flat heat source of minimal power which will result in emergence of excess temperature in point located on opposite side of sample in the form of plate heat-insulated from environment. Excess temperature and rate of its change are measured in tested point at three time moment specified in advance and sought-for heat capacity and relaxation time are found in first approximation. Examined body is exposed to power which value exceeds initial magnitude of power by value set beforehand, excess temperature and rate of its change are fixed at following three time moment in tested point and sought-for thermophysical characteristics are determined in second approximation. Then type and power of thermal action are determined by minimal of energy consumption with allowance for time of experiment as well as excess temperature and rate of its change in tested point when system is brought to preset thermal mode. Examined body is exposed to action of this power in the course of specified time interval and after this excess temperature and rate of its change in tested point at three specified time moments are measured. Finally sought-for heat capacity and relaxation time of temperature field are determined. EFFECT: enhanced authenticity of method. 1 dwg, 1 tbl
