摘要： By utilizing the process of this invention, nitrile rubber latices having solids contents of greater than 60 percent can be prepared from standard nitrile rubber latices having solids contents of less than 30 percent. The present invention more specifically discloses a process for increasing the solids content of a low solids nitrile rubber latex which comprises the steps of (1) concentrating the low solids nitrile rubber latex by removal of water therefrom to produce an intermediate solids nitrile rubber latex having a solids content which is within the range of about 35 percent to about 45 percent, wherein the low solids nitrile rubber latex has a solids content which is less than about 30 percent; (2) subjecting the intermediate solids nitrile rubber latex to a pressure which is within the range of about 3.45 x 10
6 Pa to about 6.9 x 10
7 Pa at a temperature which is within the range of about 120°F to about 170°F to produce a pressure agglomerated nitrile rubber latex; and (3) further concentrating the pressure agglomerated nitrile rubber latex by removal of water therefrom to produce a high solids nitrile rubber latex having a solids content of greater than about 60 percent.

摘要： Provided is a thermal decomposition method of used rubber that has excellent yields of isoprene and limonene without reducing the efficiency of thermal decomposition. The method is a method of thermally decomposing used rubber, including bringing the used rubber into contact with or swelling the used rubber in a medium, where the medium has a SP value of 8.3 (cal/cm3)1/2 to 11 (cal/cm3)1/2 and an endothermic peak temperature of 235 °C or higher measured by thermogravimetry (TGA), and the medium is liquid at 150 °C, and then performing thermal decomposition.
