    • An oil-based suspension-dispersion system of drag reduction polymers and the method for preparing same, characterized in adding 0.001-0.1 wt % of ultraviolet absorber and 0.001-0.1 wt % of bactericide into 50-90 wt % of vegetable oil and then mixing the obtained mixture to be homogeneous for use as dispersant, adding 2-25 wt % of separant into 10-40% of extra-high-molecular α-olefin-styrene polymer based drag reduction polymer and crushing them into powders at a temperature of lower than −90° C., based on the total weight of the suspension-dispersion system, and then adding the obtained mixture into the dispersant and stirring the mixture by using a high speed emulsion machine to make the mixture homogeneous and emulsified. The system offers a low viscosity of the suspended dispersion system, a high solid content up to 35%; improved high temperature resistance performance, higher flash point, improved safety, and good stability in storage.
    • 减阻聚合物的油基悬浮分散体系及其制备方法,其特征在于在50-90重量%的植物油中加入0.001-0.1重量%的紫外线吸收剂和0.001-0.1重量%的杀菌剂,然后混合 所得混合物均匀,用作分散剂,将2-25重量%的分离剂加入到10-40%的高分子量α-烯烃 - 苯乙烯聚合物基阻聚聚合物中,并在较低温度下粉碎成粉末 基于悬浮分散系统的总重量-90℃,然后将所得混合物加入分散剂中并通过使用高速乳液机搅拌该混合物以使混合物均匀并乳化。 该系统提供了低粘度的悬浮分散系统,高固含量高达35%; 提高耐高温性能,闪点高,安全性提高,储存稳定性好。
