THERMOFORMABLE CROSSLINKED ACRYLIC

摘要

There is provided a thermally reversible admixture comprising (a) an ionically crosslinked polymer matrix comprising at least one (meth)acrylic polymer, a first mole fraction of an acid functional polymer, a second mole fraction of a moiety capable of forming an ionic crosslink with the acid functional polymer, wherein the first mole fraction and the second mole fraction are based on the total number of moles of repeat units in the polymer matrix; and (b) 2 to 50 weight percent microspheres.
