1. (v. t.) To cause polymerization of; to produce polymers from; to increase the molecular weight of, without changing the atomic proportions; thus, certain acids polymerize aldehyde.

2. (v. i.) To change into another substance having the same atomic proportions, but a higher molecular weight; to undergo polymerization; thus, aldehyde polymerizes in forming paraldehyde.
