Anwendung

Hard and soft surface cleaners, defoamers in coatings and water treatment. Lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.

Leistungsmerkmale und Vorteile

Surface active material whose properties are dependent on the hydrophilic (EO)/hydrophobic (PO) ratio. High EO content gives better o/w stabilizers.

Physikalische Form

Terminal primary dihydroxy-functional oligomer.

The block polyethers PEO-PPO-ph-PPO-PEO (BPE) and PPO-PEO-ph-PEO-PPO (BEP) are synthesized by anionic polymerization using bisphenol A as initiator. Compared with Pluronic P123, the aggregation behaviors of BPE and BEP at an air/water interface are investigated by the surface tension and

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
