Claims
- 1. A multifunctional, lithium containing, polymerization initiating compound of the Formula: ##STR24## wherein R.sub.1 is individually selected from the group consisting of hydrogen, an alkyl hydrocarbon radical, a cycloalkyl hydrocarbon radical, alkoxy radical, and an aromatic radical with the further limitation that R.sub.1 contains from 0 to 16 carbon atoms;
- R.sub.2 is a divalent organic radical having at least 6 carbon atoms, R.sub.2 having at least one aromatic ring and the aromatic ring being directly attached to a carbon which is attached to an aromatic ring of the above formula, with the further limitation R.sub.2 contains carbon and hydrocarbon, and optionally oxygen; oxygen when present is present only in the configuration of a diphenyl oxide;

A multifunctional, lithium containing, polymerization initiating compound of the Formula: ##STR25## wherein R.sub.1 is individually selected from the group consisting of hydrogen, an alkyl hydrocarbon radical, a cycloalkyl hydrocarbon radical, alkoxy radical, and an aromatic radical with the further limitation that R.sub.1 contains from 0 to 16 atoms;
- R.sub.2 is a divalent organic radical having at least 6 carbon atoms, R.sub.2 having at least one aromatic ring, the aromatic ring being directly attached to a carbon which is attached to a lithium atom of the above formula, with the further limitation R.sub.2 contains carbon and hydrocarbon, and optionally oxygen, iron, and/or sulfur, oxygen and sulfur when present are present only in the configuration of a diphenyl oxide or diphenyl sulfide, iron in the ferrocene configuration;
- R.sub.3 is selected from the group consisting of alkyl, cycloalkyl, and aromatic radicals containing from 1 to 20 carbon atoms.
- 8. The compound of claim 7 wherein R.sub.2 contains from 6 to 12 carbon atoms.
- 9. The compound of claim 8 wherein R.sub.2 is a 1,4-phenylene radical.
- 10. The compound of claim 8 wherein R.sub.2 is a 4,4'-biphenylene radical.
- 11. The compound of claim 8 wherein R.sub.2 is a 4,4'-oxybisphenylene radical.
- 12. The compound of claim 7 wherein R.sub.3 is a secondary butyl radical.
- 13. 1,4-phenylenebis(3-methyl-1-phenylpentylidene)bis(lithium).
- 14. (1,1'-biphenyl)-4,4'diylbis(3-methyl-1-phenylpentylidene)bis(lithium).
