    摘要： The present invention provides radiation curable resin compositions having enhanced low temperature flexibility and to methods of using these compositions. The radiation curable resin compositions contain no or essentially no volatile organic components (VOCs), and find particular use as coating compositions. In particular, the radiation curable resin compositions of this invention comprise a vinyl dioxolane end-capped oligomer blended with a photoinitiator.

    摘要： A method for preparing a spiral wound filtration module is provided. The module has a central permeate carrier tube. The method includes winding at least one filtration leaf about the permeate carrier tube. The filtration leaf includes a first membrane sheet, a permeate carrier sheet, and a second membrane sheet. The winding step creates an end face extending radially outwardly from the permeate tube on each end thereof. After winding, the filtration module is maintained in a wound state. An adhesive is then supplied to each end face and a vacuum is applied through each of the permeate tube. While the vacuum is applied, the permeate tube and filtration leaf assembly are spun in a centrifuge until the adhesive has solidified. After spinning, each end face of the module is severed at a distance between the level of adhesive along the feed spacer screen and the level of adhesive along the permeate carrier sheet.
