Abstract: A process for the production of sheet material having reversible absorptivity for moisture vapor by applying polymers containing at least 5% by weight of esters of ethylenically unsaturated carboxylic acids with tertiary alcohols having four to eight carbon atoms as polymerized units to substrate materials and heating to a temperature higher than the decomposition temperature of the polymer to thereby eliminate an olefin and form free carboxylic groups in the polymer.
