Amphiphilic Copolymers Containing POSS and SBMA with N-Vinylcaprolactam and N-Vinylpyrrolidone for THF Hydrate Inhibition.

摘要: Icelike gas hydrates deposited in the pipelines under low temperatures and high pressures could remarkably reduce transport efficiency, a dosage of water-soluble polymers act as kinetic hydrate inhibitors (KHIs) to prevent formation. It was believed that hydrophobic moiety played vital role enhancing KHI performance. In this work, amphiphilic copolymers containing polyhedral oligomeric silsesquioxane (POSS) superhydrophilic sulfobetaine methacrylate (SBMA) well N-vinylcaprolactam (VCap) N-vinylpyrrolidone (VP) were prepared, an efficient effect obtained on tetrahydrofuran (THF) inhibition found. When certain amount introduced, THF analogue structure II presented prolonged induction time gave rise looser state rather than crystalline solid. Analyses low-field nuclear magnetic res...
