Abstract
The present invention provides a moisture-scavenging composition including the compound: ##STR1## wherein: R.sub.1 is a methyl group, or a branched or straight chain alkyl or alkanol group; R.sub.2, R.sub.3, R.sub.4 and R.sub.6 are, individually, a hydrogen atom, a methyl group, a straight chain or branched chain alkyl or alkanol group, a cyclic alkyl or an aryl group; R.sub.5 is a methyl or methylol group, or a branched chain or straight chain alkyl or alkanol group; R.sub.7 is a hydrogen atom, a methyl group, a straight chain or branched chain alkyl or alkanol group, a cyclic alkyl group, a carbonyl group or an aryl group, or R.sub.7 and R.sub.6 are fused together with the attached carbon to form an eight member bicyclic compound having the structure: ##STR2## wherein: R.sub.1 ' is a methyl group or a branched or straight chain alkyl or alkanol group; R.sub.2 ', R.sub.3 ', and R.sub.4 ' are, individually, a hydrogen atom, a methyl group, a straight chain or branched chain alkyl or alkanol group, a cyclic alkyl or an aryl group.
