| titleOfInvention | Initiator for producing alkali metal organic compound and polymer |
| abstract | NEW MATERIAL: An alkali metal org. compd. represented by formula I (wherein Ar 1 and Ar 2 are each aryl or hetaryl optionally having a ring fused; R is 1-7C chain alkyl or aralkyl inert to an alkali metal or alkali alkyl; m and n are each 4 or less; M is an alkali metal; and the sum total of carbon atoms of all of Rs is 3 or more). n USE: This new material is used as an anion polymn. initiator for producing a polymer of butadiene or isoprene and soluble in a hydrocarbon medium and stable and contains no monofunctional component. n PROCESS: Diarylethylidene represented by formula II (pref., 1,1-diphenylethylene, etc.), and an alkali metal M (pref., Li) are reacted in the presence of ether (pref., THF, etc.), pref. at 0-40°C under stirring. n COPYRIGHT: (C)1991,JPO |
