DEFINITION

Classification: 585/510

Definite molecular weight product, e.g., dimer, etc.:

(under subclass 502) Subject matter wherein a monoolefin product can be described by an empirical formula having only invariable subscripts.

(1) Note. The desired product may be a mixture of isomers or a restricted mixture of related compounds, e.g., a dimertrimer mixture.
