The effects of a PPO-PEO-PPO triblock copolymer (25R4, PO(19)-EO(33)-PO(19)) on thermoreversible micellization and gelation properties of a PEO-PPO-PEO triblock copolymer (F108, EO(133)-PO(50)-EO(133)) in water were studied by means of micro-DSC and rheology.

Phase Behavior and Lubricity of Aqueous PEO-PPO-PEO and PPO-PEO-PPO Triblock Copolymer Solutions
Tribology Transactions, 2016ABSTRACTAqueous triblock copolymer solutions are potential low-cost, eco-friendly lubricants. However, as a solution, their phase changes with copolymer concentration and solution temperature, raising the question, “Does the phase change affect the formation of adsorbed layer and the lubrication performance?” This article studies the copolymer solution

Local compositional fluctuations in PPO/HIPSand PPO/SBS blends
Journal of Polymer Science Part B: Polymer Physics, 1994AbstractSolid‐state NMR relaxation has been used to explore the distribution of components in poly(phenylene oxide) (PPO) high impact polystyrene (HIPS) and PPO/poly(styrene‐b‐butadiene‐b‐styrene) (SBS) blends. The nuclear relaxation of PPO in the former system is single exponential for all compositions, but the relaxation of PS in the blend is simple ...

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 dilational viscoelasticity.

Post-Pregnancy Osteoporosis (PPO)
Journal of Clinical Densitometry, 1998Individuals with back pain during or immediately after pregnancy are suspect for postpregnancy osteoporosis (PPO). These patients are often diagnosed late if at all. This case report was selected to illustrate the presentation of such patients. Common criteria include back pain, spine fractures, occurrence in late pregnancy or within 3 mo postpartum ...
