摘要:
This disclosure relates to a composition (e.g., a cleaning and/or stripping composition) containing (a) 0.5 - 25 percent by weight an alkaline compound; (b) 1 - 25 percent by weight an alcohol amine compound; (c) 0.1 - 20 percent by weight a hydroxylammonium compound; (d) 5 - 95 percent by weight an organic solvent; (e) 0.1 - 5 percent by weight a corrosion inhibitor compound; and (f) 2 -25 percent by weight water.
摘要:
This disclosure relates to a polymer that includes a first repeat unit and at least one end-cap group at one end of the polymer. The first repeat unit includes at least one imide moiety and at least one indane-containing moiety. The end-cap group is capable of undergoing a cycloreversion reaction. This disclosure also relates to a thermosetting composition containing the above polymer.
