摘要： A dispersible inorganic pigment composition in which the surface of a finely divided inorganic pigment is coated with a substance which renders the surface hydrophobic and then with a thermoplastic polymer and a process for the preparation of the composition. The composition is readily dispersible in thermoplastics and paints and it can be used to color thermoplastic materials directly, avoiding the preparation of a master batch.

摘要： A solid particulate olefin polymer containing monomer(s) dissolved therein is vigorously agitated mechanically to raise the temperature of the polymer to at least 90.degree. C. This vigorous agitation is effected in the absence of any purge gas and the unpolymerized olefin monomer desorbed from the polymer by the increase in temperature can readily be recovered and recycled to the polymerization vessel. The technique can form part of the work-up process in which the polymer is removed from the polymerization vessel and separated from unconverted monomer(s) prior to isolation. By this technique, propylene is removed from polypropylene without using a purge stream of nitrogen which makes recovery of the propylene difficult and expensive. The technique additionally heats up the polymer which can be advantageous for subsequent processing. Apparatus for effecting the process includes an agitation vessel which is connected, preferably through an intermediate separation vessel, to an olefin polymerization vessel.
