英文摘要：

[Aims] This paper aimed to synthesize a kind of agricultural spreader containing silicone with excellent performance. [Methods] Using hexamethyltrisiloxane and ally/polyethylene glycol methyl ether as raw material, bispolyetherhexamethyl trisiloxane was synthesized by hydrosilylation reaction in the present of Karstedt catalyst. Meanwhile, its structure was characterized by FT-IR and ~H NMR. [Results] After optimization of reaction conditions, the yield was 95.8%. Furthermore, the performance measurement result showed that the product had excellent interfacial properties. [Conclusions] The product is worthy of further study and popularization as agricultural spreader.
