Abstract: | Summary The receptivity of graft-polyacrolein on wood to hydroxylamine is discussed in terms of a geometric model for the voids and surfaces formed in wood by the swelling action of water. The receptivity of the carbonyl group of graft-polyacrolein varies inversely with the number of graft sites. This relationship is a consequence of decrease in the spacing between graft chains on the primary surface. The receptivity increases gradually with an increase in the amount of graft polymer, and this is a result of the swelling action of graft-polyacrolein which extends to the microscopically visible macropores of wood. |
