Plum-pudding resins

Plum pudding resins are prepared from micro-bead particles of commercial resins, De-Acidite (1-10 pm) and Zeo-Karb 226 (5-10 pm) and a variety of polymers such as cellulosics, ionically crosslinked polysalts, or poly(vinyl alcohol) cross-...

While the thermally regenerable plum pudding resins can be classified as composite resins without ambiguity, the authors are of the opinion that it may not be appropriate to use such a classification for thermally regenerable no-matrix resins. Unlike the plum pudding resin, which is obtained by blending two independent resins in an inert matrix, the no-matrix resin is devoid of aify inert matrix and refers to a polymer matrix in which the weakly acidic and weakly basic domains are segregated.
