摘要： The present disclosure provides methods for producing an olefin polymer including: i) contacting alpha-olefin with a first catalyst system comprising a first non-metallocene catalyst, a first activator, and a reversible chain transfer agent to form a first polymer; ii) contacting the first polymer with a coupling agent in the presence of a catalyst, an activator; and iii) obtaining a second polymer. The present disclosure further provides polymers having a g′vis value from about 0.4 to about 0.8 and a vinyl unsaturation content of 0.8 or greater vinyls/1000 carbons, and preferably low gel content.

摘要： A functionalized polyolefin and a tire tread composition comprising the functionalized polyolefin is described. The functionalized polyolefin comprises a vinyl/vinylidene-terminated polyolefin in which the vinyl/vinylidene terminus is functionalized with an alkoxysilane or an alkylsilane and optionally having ether, hydroxyl and/or amine functionality. The invention is also directed to the synthesis of vinyl/vinylidene-terminated polyolefins, functionalization at the vinyl/vinylidene terminus with an alkoxysilane or an alkylsilane and optionally having ether, hydroxyl and/or amine functionality.

摘要： Provided herein are various methods for forming alkylaromatic sulfonate compositions and blended alkylaromatic sulfonate compositions, and such compositions themselves. The methods of various embodiments include obtaining a C8-C30 hydrocarbon mixture, optionally treating the mixture to concentrate the mixture in sulfonatable aromatics, and sulfonating the mixture to form the alkylaromatic sulfonates. The mixture or treated mixture may be blended with linear alkyl benzene (LAB) compositions and sulfonated, and/or the alkylaryl sulfonates may be blended with linear alkylbenzene sulfonate (LAS) compositions, to form the blended alkylaromatic sulfonates of some embodiments. These compositions and processes for making them may be tailored to serve a variety of end uses, such as detergents in cleaning solutions or for enhanced oil recovery operations, and/or as low foaming and/or hydrotropic additives in detergent formulations, and the like.
