Abstract
Propylene polymers of 12 to 24 carbon atoms are prepared by dimerizing propylene polymers of 6 to 12 carbon atoms at 0-100 DEG C. in the presence of a preformed boron trifluoride-ether complex and excess boron trifluoride. The starting polypropylene may be a narrow fraction of a simple propylene polymerization product. Specified ethers which may be used in the complex are dimethyl, diethyl, diisopropyl, methyl ethyl and methyl tertiary butyl ethers. The amount of complex used may be 1 to 10 weight per cent of the polypropylene to be dimerized. Excess boron trifluoride is maintained by passing the gas through the reaction mixture. Pressures of 1 to 10 atmospheres may be used to maintain liquid phase conditions. Batch or continuous operation can be used. The catalyst can be decomposed with water and the oily product separated from the aqueous layer and fractionated to obtain the desired dimer from unconverted material and any other products formed. Examples illustrate the dimerization of a C9 and a C12 propylene polymer cut using a complex of ethyl ether and boron trifluoride containing 45 weight per cent of boron trifluoride at 60-70 DEG C. for four hours, boron trifluoride gas being slowly passed through the reaction mixture throughout the reaction period.
