Effect of Preparation Conditions on Crosslinking Behavior of Linseed Oil-Based Thermosetting Polymer

Bio-based materials have received more attention to replace from petroleum resources because of sustainability reason. Plant oil is one the most interesting raw produce thermosetting polymer. A crosslinking reaction between epoxidized linseed and vegetable oil-based crosslinkers investigated in present study. Two types crosslinker including fatty acid dimer trimer were reacted with oil. rotational rheometer equipped cone-and-plate geometry was used monitor progress three-dimensional network formation. curing phenomenon illustrated by increment storage modulus mixture. The trifunctional effective than difunctional for an uncatalyzed systems at temperature 120 OC. When trimer-crosslinker system increased OC 140 OC, induction time decreased around three times. obviously accelerated using 4-methyl amino pyridine as a catalyst. Increasing catalyst content induced monotonically reduction process. 2% only 18 minutes, which significantly shorter that seven
