ABSTRACT:
This invention provides a novel catalyst composed of a complex of an organic acid or its ester and a Lewis acid, preferably boron trichloride that can add olefin monomers to increase the molecular weight of the complex from as low as 200 to in excess of a million, with the complex being active viz., living, until the complex dies, viz., is decomposed or destroyed so that polymers in the liquid or easily liquefiable range of 300 to about 20,000 can be made or those more difficult to be liquefied or unliquefiable, viz., those of over 10,000 up to 100,000 or in some cases 500,000 and then those in the range of the elastomers, or moldable or extrudable plastics range having very high molecular weights, generally in excess of 100,000 up to in excess of 500,000 and having useful end groups such as the halogens and specifically chloride, allyl, acryl or methacryl, acetate or formate to name some of the more useful ones.
