K1 values of the tetrabutylammoniumsalts increase with decreasing hydrogenbonding strength in triethylammoniumsalts. The measured enthalpies of rearrangement and those calculated from the ν(N+H) bands of hydrogen-bonded complexes studied are in agreement. It has also been shown that tetrabutylammonium salt anions can participate in the rearrangement of hydrogen-bondedionpairs like the organic
Polymers having polyolefin segments as the side chain, with a structural unit represented by the following Formula (1):
wherein A is an olefin polymer having a weight average molecular weight of 400 to 500,000; R is H, an alkyl group, or an aralkyl group; W and Z are each O, HN, or S; and x and y are each 0 or 1, with the proviso that at least one of them is 1. The polymer can be applied as an antistatic agent, a cosmetic additive, a releasing agent for toner, a pigment dispersant, a lubricant for vinyl chloride resins, a coating material, an emulsion composition and the like.
