Pigmented polymer compositions and processes for preparing melt-processible polymer compositions contain a melt-processible polymer, surface treated organic pigment, typically titanium dioxide, and a polymer processing aid are described. The pigment is surface treated by contact with a silicon-containing compound, such as octyltriethoxysilane followed by contact with an organic compound such as isostearic acid or ethoxylated silicone. The pigmented polymer composition containing a polymer processing aid facilitates production of shaped articles with low melt fracture.

The present invention discloses a method for separating and extracting isostearic acid from monomer acid. The present invention relates to a method for separating and extracting isostearic acid, in particular to a novel method for separating and extracting isostearic acid from monomer acid. The present invention provides a method for separating and extracting isostearic acid from monomer acid, which is suitable for use in commercial production. The method is characterized in: esterify the byproduct (monomer acid) obtain in production of dimer acid through bleaching earth catalytication process under medium pressure without catalyst to obtain monomer acid ester, treat by catalytic hydrogenation under medium pressure, and filter to obtain hydrogenised monomer acid ester; envelope with carbamide, filter, separate, and wash with water to obtain crude product of isostearic acid ester; perform molecular distillation to obtain refined isostearic acid ester, and then perform hydrolysis to obtain isostearic acid. Compared to the separation and extraction technique in the prior art, the present invention has the following advantages: the acidity and viscosity are low during hydrogenisation, and therefore the service life of catalyst is long, no nickel soap will be formed, and the corrosion to equipment is reduced; the product can be enveloped and separated by carbamide more easily; the distillation can be performed at a lower temperature; the iodine value of final product is low, the color is light, and the purity is high.
