Class Information
Number: 526/123.1
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 > Polymerizing in the presence of a specified material other than monomer > Material contains transition metal or compound thereof > Material contains compound of group ia (li, na, k, rb, cs, fr) or group iia (be, mg, ca, sr, ba, ra) metal wherein ia or iia metal is not bonded to hydrogen or to carbon
Description: Subject matter wherein the specified material contains a transition metal compound which is in admixture with a Group IA or IIA metal compound, which compound is other than a Group IA or Group IIA metal hydride or compound containing a Group IA or Group IIA metal atom bonded directly to a carbon atom; or wherein a transition metal-containing compound additionally contains at least one Group IA or Group IIA metal atom in the same molecule, which Group IA or Group IIA metal atom is not bonded directly to a hydrogen or carbon atom (e.g., Ca(NR2
