摘要： In the treatment, a reverse osmosis membrane element having a polyamide skin layer is loaded in a pressure vessel in a membrane separator and contacted with a bromide-containing aqueous solution of free chlorine. The thus treated reverse osmosis membrane element retains for a long time its effect of reducing solute concentration in a solution treated with the reverse osmosis membrane and rejects efficiently non-electrolytic organic materials or substances such as boron that will not be dissociated in a neutral region. A reverse osmosis membrane module having the thus treated reverse osmosis membrane element is provided as well.

摘要： The instant invention is a pressure sensitive adhesive composition comprising an ultra-high solid polyurethane dispersion. The ultra-high solid polyurethane dispersion comprises (1) a first component comprising a first polyurethane prepolymer comprising the reaction product of a polyol and polyisocyanate, (2) a second component comprising a media phase selected from the group consisting of a second polyurethane prepolymer emulsion, a low solid content polyurethane dispersion, a seed latex, and combinations thereof; and (3) optionally a chain extender. The ultra-high solid polyurethane dispersion has at least a solid content of at least 60 percent by weight of solid content, based on the total weight of the ultra-high solid polyurethane dispersion, and a viscosity of less than 5000 cps at 20 rpm at 21° C. using spindle #4 with Brookfield viscometer.
