摘要： A method is provided for the direct synthesis of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cyano, carbonylamino or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or of tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.

摘要： A multistep process is disclosed for the manufacture of synthetic lubricants from the C.sub.8 to C.sub.24 linear olefin components of below liquid fuel value petroleum distillate fractions derived via the high temperature thermal cracking of petroleum residua. Such feeds contain major amounts of 1-n-olefins, n-paraffins and greater than 0.1% concentration of sulfur mostly in the form aromatic, thiophene type sulfur compounds.In the first step of the present process such feeds are enriched in the straight chain aliphatic hydrocarbon components by one or more separation processes, preferably via urea adduction or by crystallization. In the second step, the olefin components are oligomerized to sulfur containing C.sub.30 to C.sub.60 polyolefins, preferably in the presence of BF.sub.3 complex catalysts. In the third step, the polyolefins are hydrogenated to novel isoparaffin lubricants in the presence of sulfur resistant catalysts, preferably transition metal sulfides.
