Synthesis of oligomeric cyanate esters |
| 摘要 |
A cyanate ester system is disclosed. An aryl ether oligomer may be made from a dihydroxyaromatic compound and a dihaloaromatic compound in the presence of a base. The oligomer is then reacted with a cyanide compound in the presence of a base to form the cyanate ester shown below. The cyanate ester may then be cross-linked to a thermoset having triazine ring cross-links <?in-line-formulae description="In-line Formulae" end="lead"?>HO-Ar<SUP>2</SUP><img id="PRIVATE-USE-CHARACTER-00001" he="7.20mm" wi="8.47mm" file="US07342085-20080311-Parenopenst.TIF" alt="private use character Parenopenst" img-content="character" img-format="tif" />O-Ar<SUP>1</SUP>-O-Ar<SUP>2</SUP><img id="PRIVATE-USE-CHARACTER-00002" he="7.20mm" wi="8.47mm" file="US07342085-20080311-Parenclosest.TIF" alt="private use character Parenclosest" img-content="character" img-format="tif" /><SUB>n</SUB>OH.<?in-line-formulae description="In-line Formulae" end="tail"?>
