Abstract
A method of manufacturing a monomer composition includes a step of mixing a zinc catalyst (A), an iso(thio)cyanate compound (B) having an iso(thio)cyanate group, and an alcohol compound (C) having a hydroxy group, and at least one of the iso(thio)cyanate compound (B) or the alcohol compound (C) has a (meth)acryloyl group.

A method of manufacturing a monomer composition, comprising mixing a zinc catalyst (A), an iso(thio)cyanate compound (B) having an iso(thio)cyanate group, and an alcohol compound (C) having a hydroxy group, and
- reacting the iso(thio)cyanate compound (B) having an iso(thio)cyanate group and the alcohol compound (C) having a hydroxy group in the presence of the zinc catalyst (A) to obtain the monomer composition containing urethane (meth)acrylate that is a reaction product, wherein at least one of the iso(thio)cyanate compound (B) or the alcohol compound (C) has a (meth)acryloyl group and in a case in which the iso(thio)cyanate compound (B) does not have the (meth)acryloyl group, the alcohol compound (C) consists of a compound that has the (meth)acryloyl group, and
- wherein the alcohol compound (C) is at least one selected from the group consisting of 2-hydroxyethyl(meth)acrylate, 2-hydroxypropyl(meth)acrylate, 2-hydroxybutyl(meth)acrylate, 2-hydroxy-3-phenoxypropyl(meth)acrylate, 4-hydroxybutyl(meth)acrylate, and 1,4-cyclohexanedimethanol mono(meth)acrylate.
A raw material composition, comprising:
- a zinc catalyst (A), an iso(thio)cyanate compound (B) having an iso(thio)cyanate group, and an alcohol compound (C) having a hydroxy group, wherein at least one of the iso(thio)cyanate compound (B) or the alcohol compound (C) has a (meth)acryloyl group,
- wherein a molar ratio of the hydroxy group in the alcohol compound (C) to the iso(thio)cyanate group in the iso(thio)cyanate compound (B) (that is, molar ratio [hydroxy group/iso(thio)cyanate group]) is from 0.8 to 1.2 and in a case in which the iso(thio)cyanate compound (B) does not have the (meth)acryloyl group, the alcohol compound (C) consists of a compound that has the (meth)acryloyl group, and
- wherein the alcohol compound (C) is at least one selected from the group consisting of 2-hydroxyethyl(meth)acrylate, 2-hydroxypropyl(meth)acrylate, 2-hydroxybutyl(meth)acrylate, 2-hydroxy-3-phenoxypropyl(meth)acrylate, 4-hydroxybutyl(meth)acrylate, and 1,4-cyclohexanedimethanol mono(meth)acrylate.
A monomer composition containing a zinc catalyst (A) and a (meth)acrylate compound (D) that is a reaction product of an iso(thio)cyanate compound (B) having an iso(thio)cyanate group, and an alcohol compound (C) having a hydroxy group, wherein a molar ratio of the hydroxy group in the alcohol compound (C) to the iso(thio)cyanate group in the iso(thio)cyanate compound (B) (that is, molar ratio [hydroxy group/iso(thio)cyanate group]) is from 0.8 to 1.2 and in a case in which the iso(thio)cyanate compound (B) does not have the (meth)acryloyl group, the alcohol compound (C) consists of a compound that has the (meth)acryloyl group, and
- wherein the alcohol compound (C) is at least one selected from the group consisting of 2-hydroxyethyl(meth)acrylate, 2-hydroxypropyl(meth)acrylate, 2-hydroxybutyl(meth)acrylate, 2-hydroxy-3-phenoxypropyl(meth)acrylate, 4-hydroxybutyl(meth)acrylate, and 1,4-cyclohexanedimethanol mono(meth)acrylate.
