DEFINITION

Classification: 524/490

Hydrocarbon having a specified name molecular weight or chain length:

(under subclass 474) Subject matter wherein the designated nonreactant material is named a hydrocarbon, or one having either a claimed numerical weight or a claimed specified chain length (the number may also reflect a range or average).

(1) Note. The molecular weight may be expressed in any of the art-recognized terms or units, e.g., viscosity-average vapor pressure osmometry, weight average, etc., and the chain length may be linear, cyclic, or branched.
