Class Information
Number: 526/336
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > Polymers from only ethylenic monomers or processes of polymerizing, polymerizable compositions containing only ethylenic monomers as reactants or processes of preparing > From hydrocarbon monomer containing at least two ethylenic groups, e.g., butadiene, etc. > Ethylenic groups are non-conjugated, e.g., divinylbenzene, etc.
Description: Subject matter wherein two or more ethylenically unsaturated groups are (1) separated from each other either by an aromatic ring (e.g., divinyl benzene), or (2) separated by at least one carbon atom of an acyclic carbon chain which carbon atom is not part of a methine group (e.g., -C=C-C-C=C-, etc.), or (3) wherein two ethylenically unsaturated groups share a single carbon atom (e.g.,C=C=C , etc.).
