DEFINITION

Classification: 526/165

(under subclass 159) Subject matter wherein a nontransition metal compound which has at least one nontransition metal to carbon contains (1) at least two atoms of the same nontransition metal; or (2) at least two diverse nontransition atoms, (e.g., Sb(C2H5)4ClAl2(C2H5)6, LiAlR4, etc.).

(1) Note. Included herein are those compounds that contains a repeat unit (e.g., (CH2[end subscrpt]AlR)n, etc.).
