| abstract |
A liquid hydrocarbon composition, containing paraffinic hydrocarbon components in which the extent of branching, as measured by the percentage of methyl hydrogens (BI), and the proximity of branching, as measured by the percentage of recurring methylene carbons which are four or more carbons removed from an end group or branch (CH 2 >4), are such that: n (a) BI-0.5(CH 2 >4)>15; and n (b) BI+0.85(CH 2 >4)<45 n as measured over said liquid hydrocarbon composition as a whole. |
