Claims6
A process to make a homopolymer wherein said homopolymer consists essentially of 3-ethyl-1-hexene, and wherein said homopolymer has a melting point in the range of about 425.degree. C. to about 435.degree. C., said process comprising polymerizing 3-ethyl-1-hexene with a catalyst system that consists essentially of:
- (1) a titanium trihalide (TiX.sub.3) wherein each X is selected from the group consisting of fluorine, chlorine, bromine, and iodine, and
- (2) an alkyl aluminum halide (AlR.sub.n X.sub.(3-n)) wherein
- (a) each R is a hydrocarbon radical containing 1 to 18 carbon atoms, and wherein
- (b) each X is selected from the group consisting of fluorine, chlorine, bromine, and iodine, and wherein
- (c) n is either 1 or 2.
A process to make a homopolymer wherein said homopolymer consists essentially of 3-ethyl-1-hexene, and wherein said homopolymer has a melting point in the range of about 425.degree. C. to about 435.degree. C., said process comprising polymerizing 3-ethyl-1-hexene at a temperature in the range of about 60.degree. C. to about 120.degree. C. with a catalyst system that consists essentially of titanium trichloride and diethyl aluminum chloride.
