Abstract
A method for making a monomer includes reacting an alkanol-substituted phenol with epihalohydrin in the presence of a phase transfer catalyst at a temperature of 50° C. or lower to produce a first intermediate product. The method further includes removing excess epihalohydrin, and after removing excess epihalohydrin, contacting the first intermediate product with a base to produce a second intermediate product, and forming an oxirane-functional vinyl monomer from the second intermediate product. The monomer includes an oxirane group, an unsaturated vinyl bond, and optionally an aromatic spacer between the two functional groups.
Claims26
A method for making a monomer, the method comprising:
- reacting an alkanol-substituted phenol with epihalohydrin in the presence of a phase transfer catalyst (preferably a quaternary ammonium salt or quaternary phosphonium salt) at a temperature of 50° C. or lower to produce a first intermediate product;
- removing excess epihalohydrin;
- after removing excess epihalohydrin, contacting the first intermediate product with a base to produce a second intermediate product;
- and
- forming an oxirane-functional vinyl monomer from the second intermediate product.
A monomer composition comprising 80 wt-% or more of a compound of Formula (III):
- wherein each R1 is independently a carbon-containing group,
- wherein n is 0 to 4, and
- wherein R4 is a carbon-containing group.
