Abstract
A process for preparing a resin having a low iodine value, comprising treating a resin having a residual unsaturated bond with a cationic polymerization catalyst. According to the process, a resin in which residual unsaturated bonds are decreased can be prepared, and the obtained resin having a low iodine value can be suitably used as raw materials for flame retarders, adhesives and the like.
Claims13
A process for preparing a resin having a low iodine value, comprising treating a resin having a residual unsaturated bond in its molecule with a cationic polymerization catalyst, said resin obtained by polymerizing at least one of an aromatic monomer, and .alpha.-olefin having 3 to 22 carbon atoms and a (meth)acrylic acid ester.
A process for decreasing an iodine value of a resin having a residual unsaturated bond and obtained by polymerizing at least one of an aromatic monomer, an .alpha.-olefin having 3 to 22 carbon atoms and a (meth)acrylic acid ester, which comprises treating said resin with a cationic polymerization catalyst and lowering said iodine value of said resin, wherein the resulting resin with a lower iodine value is not colored by reaction with a halogen-containing compound.
