摘要

A PROCESSP UNDERSTANDING HEATING A MILK-CONTAINING MIXTURE TO ONE OR MORE TEMPERATURES OF AT LEAST ABOUT 90 DEGREES AND AT LEAST ONE OR MORE SUFFICIENT PRESSURES TO MAKE SUBSTANTIALLY THE MIXTURE IN THE NET Phase; A process for the anionic polymerization of at least one styrenic monomer in which at least one lithium-starter is used to produce a styrenic polymer in a product solution; AND IMPROVEMENT. The present invention provides a process comprising heating a lithium-containing mixture to one or more temperatures of at least about 90 ° C, and one or more pressures sufficient to substantially maintain the entire mixture in the liquid phase. The lithium-containing mixture comprising water, lithium ions, at least one saturated liquid hydrocarbon and at least one styrenic polymer formed by anionic polymerization. The amount of water is at least about 10 by weight average molecular weight of at least about 1000.
