With the increase of the chaiii from three to six carbons, the gelation time decreased, from 974 minutes for allylglycerol to 900 for erythritol, to 602 for pentitols, and 502 for hexitols. On the other hand, the rate of oxygen absorption'decreased with the increase of the length of carbon chain. The relation between the coniiguration and the ...
