General description
聚合物的表面活性取决于 EO/PO 比率。与普朗尼克®表面活性剂相比，PPG-PEG-PPG 表现出较低的起泡性、较大的消泡性和较低的凝胶化倾向。PPG-PEG-PPG 的末端仲羟基与普朗尼克表面活性剂中的伯羟基相比，具有较低的反应活性和酸性。
Application
PPG-PEG-PPG 普朗尼克® 31R1 可作为表面清洗剂（软质和硬质）、涂料中的消泡剂、水处理中，金属加工中的润滑剂，线性和交联聚酯和聚氨酯的消泡剂和填充剂。
软硬表面兼用型清洁剂，涂料和水处理用消泡剂。金属加工润滑剂、消泡助剂以及用于线性和交联聚酯及聚氨酯的扩链剂。
Features and Benefits
表面活性取决于EO/PO比。相比Pluronic®表面活性剂，低起泡、高消泡、更难形成凝胶。端基为二级羟基（二级醇），反应性和酸性低于Pluronic®表面活性剂的一级羟基。

Polyplex particles formed with plasmid DNA (pDNA) and Pluronic P85-block-poly{N-[N-(2-aminoethyl)-2-aminoethyl]aspartamide} (P85-b-P[Asp(DET)]) demonstrated highly effective transfection ability compared to PEG-based block cationomer, PEG-b-P[Asp(DET)]. Ternary polyplexes comprising PEG-b-P[Asp(DET)], poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide)-b-P[Asp(DET)] (P(EPE)-b-P[Asp(DET)]) used as an analog of P85-b-P[Asp(DET)], and pDNA were
