CPC: Monomers containing a branched unsaturated aliphatic radical or a ring substituted by an alkyl radical

Full Title

Full titles differ between systems:

IPC:

Homopolymers or copolymers of compounds having one or more unsaturated aliphatic radicals, each having only one carbon-to-carbon double bond, and at least one being terminated by an aromatic carbocyclic ring > Monomers containing only one unsaturated aliphatic radical > containing one ring > Hydrocarbons > containing a branched unsaturated aliphatic radical or an alkyl radical attached to the ring

CPC:
