Abstract
A moisture-scavenging composition including a mixture of moisture scavenging compounds, wherein the mixture consists of from 0 to 100 mole percent of an iminoalcohol compound: ##STR1## wherein: R.sub.1 is a methyl or methylol group, an ethyl or ethylol group, a branched or straight chain alkyl or alkanol group, a cycloalkyl group, or an aryl group; R.sub.2 is a hydrogen atom, a methyl or methylol group, an ethyl or ethylol group, a straight chain or branched chain alkyl or alkanol group, a cycloalkyl group, or an aryl group, or R.sub.1 and R.sub.2 are fused together with the attached carbon to form a cycloalkane ring; R.sub.3, R.sub.4 and R.sub.5 are, individually, a hydrogen atom, a methyl or methylol group, an ethyl or ethylol group, or a straight chain or branched chain alkyl or alkanol group; R.sub.6 is a hydrogen atom, a methyl group, an ethyl group, or a straight chain or branched chain alkyl group; and R.sub.7 is a hydrogen atom, a methyl or methylol group, an ethyl or ethylol group, a straight chain or branched chain alkyl or alkanol group, a cycloalkyl group, an acyl group or an aryl group; and PA1 from 0 to 100 mole percent of an oxazolidine compound having the structure:…
