Abstract

525,542. Hydrocarbon polymerization products. JOHNSON, G. W. (I.G. Farbenindustrie Akt.-Ges.). July 4, 1938, Nos. 19775 and 20666. [Class 2 (iii)] Polymerization products are prepared by treating isobutylene, or mixtures of the same with a minor proportion of diolefines, with boron trifluoride as catalyst, at temperatures below - 10‹ C. in the presence of a diluent and of .001 to 1 per cent. (calculated on the weight of the isobutylene) of one of the following accelerators, viz.: sulphuric, nitric, caproic or trichloracetic acid ; formaldehyde, phenol, cresol or a monohydric aliphatic, cycloaliphatic or aromatic alcohol, e.g. methanol, ethyl, isobutyl, octyl or benzyl alcohol, or cyclohexanol, the accelerator being added to the isobutylene or mixture thereof before the addition of the catalyst. Specified diolefines are butadiene,. isoprene and dimethylbutadiene. In examples (1) to (7) liquid isobutylene mixed with liquid ethylene is treated at -103‹ C. with boron fluoride in the presence of one of the accelerators specified above, and in examples (8) to (10) liquid isobutylene containing a small proportion of isobutyl alcohol or cyclohexanol is mixed with butadiene, cooled by the addition of liquid ethylene and/or methane, treated with boron fluoride, dissolved in liquid ethylene or methane. The interpolymers of isobutylene and butadiene may be vulcanized by heating with gas black, zine oxide, sulphur, stearic acid, mercaptobenzothiazole and tetramethylthiuramdisulphide. Specifications 401,297, 432,310, 479,478 and 491,739 are referred to.
