Round 16: Tossup 14

Metals dry a class of these substances formed from condensing poly·ols, di·basic acids, and fatty acids. Prepreg forms of these substances that are B-staged are often used in out-of-autoclave methods. DuPont’s Amber series of these substances evolved from two hydrophobic brands of them, Dowex and Amberjet. Styrene–di·vinyl·benzene (10[2])is used in one of these substances that acts as a solid, reusable scavenger. A chloro·methyl group acts as an anchor in one of these substances (10[1])that is used as a support in solid-phase peptide (-5[1])synthesis. (10[1]-5[2])Like (10[1])that type of these substances named for Merrifield, (10[1])porous (-5[1])beads made from a class (10[1]-5[1])of these substances (-5[1])facilitate (-5[1])ion exchange. (-5[2])Hardeners (10[1])cure a class (10[1])of these substances (-5[1])made of epoxy polymers. For 10 points, what class (10[1])of viscous (-5[1])organic (-5[1])substances is named for a sticky fluid (10[1])exuded by trees? (10[1])■END■ (10[10]0[3])

ANSWER: resins [accept epoxy resins or Merrifield resins or scavenger resins or alkyd resins or ion-exchange resins]
