    • A process to prepare a relatively inexpensive utility fluid comprises contacting together ethylene and a coordination-insertion catalyst and, optionally, an alpha-olefin, in a continuously-fed backmixed reactor zone under conditions such that a mixture of a hyperbranched oligomer and a branched oligomer is formed. The hyperbranched oligomer has an average of at least 1.5 methine carbons per oligomer molecule, and at least 40 methine carbons per one-thousand total carbons, and at least 40 percent of the methine carbons is derived from the ethylene, and the average number of carbons per molecule is from 25 to 100, and at least 25 percent of the hyperbranched oligomer molecules has a vinyl group and can be separated from the branched oligomer, which has an average number of carbons per molecule of up to 20. The coordination-insertion catalyst is characterized as having an ethylene/octene reactivity ratio up to 20 and a kinetic chain length up to 20 monomer units.
    • 制备相对廉价的实用流体的方法包括在连续供给的反混混合反应器区域中将乙烯和配位插入催化剂和任选的α-烯烃在一起使得超支化低聚物和支链低聚物的混合物 形成了。 超支化低聚物每个低聚物分子平均具有至少1.5个次甲基碳,每千个总碳中至少有40个次甲基碳,至少40%的次甲基碳源自乙烯,平均碳数 每个分子为25至100,并且至少25%的超支化低聚物分子具有乙烯基并且可以与支化低聚物分离,其具有每分子平均碳数高达20个。配位插入催化剂 其特征在于具有高达20的乙烯/辛烯反应性比和至多20个单体单元的动力链长度。
