DEFINITION

Classification: 507/125

Carbocyclic ring is attached directly or indirectly to the ethylenic monomer by nonionic bonding (e.g., styrene, vinyl toluene, etc.):

(under subclass 118) Composition wherein said polymer contains a carbocyclic ring which is attached to an ethylenic moiety directly or indirectly by nonionic bonding.

(1) Note. A composition with a carbocyclic ring as part of a mere counterion to an ethylenic moiety is not a basis for including such a composition in this subclass. For example, a tetraphenylammonium poly(vinyl phosphonate) is classified in subclass 118. An additional crossreference in subclass 129 is highly recommended (see subclass 100, (5) Note).
