Abstract
945,122. Polymerizing conjugated dienes. PHILLIPS PETROLLEUM CO. April 4, 1962 [Sept. 11, 1961], No. 12921/62. Heading C3P. Polymers of conjugated dienes are made by polymerizing a monomeric material comprising a conjugated diene having four to twelve carbon atoms in the presence of an organolithium initiator, and a halogen compound selected from (1) RX z , (2) HX, or (3) X 2 , where X is a halogen, z is one, two, or three, and R is an aliphatic, cycloaliphatic, or aromatic hydrocarbon radical and when z is 2 or 3, no more than one X is fluorine, and when z is 1 and X is fluorine, R is an aliphatic hydrocarbon or cycloaliphatic hydrocarbon radical. The halogen compound may be fluorine, chlorine, bromine, iodine, HF, HBr, HCl. HI, MeCl, MeBr, CH 2 Br, CHCl 3 , CHBr 3 , ethylene bromide, allyl bromide, isopropyl iodide, isobutyl iodide, n-butyl chloride, n-butyl bromide, n-hexyl iodide, n-hexyl fluoride, 2,4,6-trichloro-1-octene, n-dodecyl chloride, 1,2,3- tribromopropane, diiodomethane, 1,4-dichloropentane, 1,3,5,-triiodopentane, 1,12-dibromo-6- dodecene, 1,5-dibromo-5-fluorononane, 1,3,6- trichloro-2,4- diethylhexane, 1,3,6-trichloro-2,4- diethylhexane, cyclopentyl fluoride, 1,3,5-tribromocyclopentane, cyclohexyl iodide, 4-methylcyclohexyl fluoride, 4-bromocyclohexane, bromobenzene, chlorobenzene, 1,5-dibromo -3,6- diisopropylbenzene, 1,4-dichlorobenzene, 4-iodotoluene, or benzyl chloride. The Specification contains an extensive list of organolithium compounds such as mono- and polylithium hydrocarbons. Exemplified lithium compounds are lithium methylnaphthalene, and dilithium dihydroanthracene by the reaction of n-butylithium and dihydroanthracene. The conjugated diene may be 1,3-butadiene, isoprene, 2,3-dimethyl - 1,3-butadiene, 1,3-pentadiene and other higher dienes, as well as halogen and alkoxy substituted dienes such as chloroprene, fluoroprene, and 2- methoxy -1,3-butadiene. The dienes are copoly- merizable with monomers containing a CH 2 = C# group such as ethylene, propylene, butenes, cyclohexene, styrenes, acrylics, and vinyl pyridenes, and also non-conjugated dienes. The polymers have mainly a cis-1,4-structure.
