Low molecular weight polyacetals are prepared by reacting an acetal-containing reagent with a polyalcohol (e.g., glycerol or sucrose), a polyamine (e.g., 3,3'-diamine-N-methyl dipropylamine or ethylene diamine), a polyester (e.g., triethyl citrate), or a polyhalide (e.g., pentaerythrityl tetrabromide). Low molecular weight polyaldehydes are prepared by converting the acetal groups of the low molecular weight polyacetal to aldehyde groups or by reacting an aldehyde-containing reagent (e.g., glyoxal) with a polyamide.
