Peroxide catalyzed polymerization of styrene in pure fatty methyl esters

A comparative study of the reactivity of three plant oil methyl esters with divinylbenzene by FTIR spectroscopy

“…It could be concluded that the difference of fatty acid compositions (listed in Tab. 1) led to the different reactivity of fatty esters, which agrees with the literature [10]. These results should be helpful for us to select oils and fats for preparing functional polymers.…”

“…4, A 708 /A 1738 decreased with the increasing amount of every oil methyl esters, most rapidly with the amount of TOM, and most slowly with the amount of SBOM, which indicated that TOM had strongest reactivity with DVB and SBOM had weakest reactivity of the three oil methyl esters. According to the results obtained in the polymerization of styrene in the presence of the fatty esters by Harrison and Tolberg [10], the fatty esters which had conjugated unsaturation could copolymerize with styrene; the non-conjugated polyene fatty esters behaved chiefly as chain modifiers and did not do this through chain transfer; and the saturated and mono-unsaturated esters behaved in a neutral fashion, serving as solvents for the monomer and polymer. As for the three plant oils we used in the polymerization, TOM contained a lot of conjugated unsaturated acids, LOM contained a lot of non-conjugated polyene fatty acids, and SBOM was composed of much amount of non-conjugated diene fatty acids.…”

“…Many investigators have published results of studies of free radical polymerization of styrene in the presence of plant oils and their derivatives [10]. Representatively, Harrison and Tolberg [10] determined the effect of each of several different fatty esters on the polymerization of styrene.…”

“…Representatively, Harrison and Tolberg [10] determined the effect of each of several different fatty esters on the polymerization of styrene. Then they reached the following conclusions.…”

Waterborne Coatings Based on Renewable Oil Resources: an Overview

“…The numbers of fatty esters per polymer mol were respectively 0.64, 1.7, 3.0, 14.5, 12.1, and 1.1. The data indicate that styrene does copolymerize with fatty esters that have conjugated unsaturation and non-conjugated fatty esters; however, both saturated and monounsaturated esters behave in a neutral fashion, serving as solvents for the monomers and polymers, with only small amounts of the esters being included in the polymer [22]. Certain catalysts are effectively used for the isomerization of vegetable oils to conjugated forms.…”
