DEFINITION

Classification: 528/395

(under subclass 1) Subject matter under Class 520, ... involving polymers derived from a heavy metal- or aluminum-containing reactant wherein a heavy metal or aluminum atom is devoid of any bonding to hydrogen or to carbon or processes of polymerizing; polymerizable compositions containing as a reactant a heavy metal or aluminum containing reactant, wherein a heavy metal or aluminum atom is devoid of any bonding to hydrogen or to carbon or processes of preparing.

(1) Note. A heavy metal denotes a metal atom having a specific gravity greater than four.

9, for a heavy metal- or aluminum- containing reactant wherein a heavy metal or aluminum atom is bonded to at least one atom of carbon or hydrogen.

480+, for processes of preparing a polymer not involving a chemical modification of the polymer, by the addition of a material thereto, and for chemically modifying material other than the polymer. Subclasses 480+ also provide for processes of admixing with a broadly claimed nonreactant material.
