Embodiment 1

[0034] 150 g of dimethyl sulfoxide, trimethylolpropane ethyloxy addition Alcohol body (in the above formula (II), p+q+r=4) 50 g, as a catalyst, 30 mol% of potassium hydroxide with a purity of 95% by weight was added to the raw material alcohol. While stirring, nitrogen gas was flowed in to replace the inside of the reaction container with nitrogen, and then the reaction container was sealed, and acetylene gas was added into the reaction container at a pressure of about 0.18 MPa. Then, while maintaining the gauge pressure at about 0.18 MPa, the temperature inside the reaction vessel was raised to 120° C., and the reaction was performed at a reaction temperature of 120° C. until the consumption of acetylene decreased. During this period, acetylene gas was gradually added to keep the pressure in the reaction vessel at about 0.18 MPa. After the reaction was completed, the residual acetylene gas was blown off to obtain 209 g of the reaction liquid. Then the reaction solution was ...

Embodiment 2

[0036] The reaction was carried out in the same manner as in Example 1 except that the raw material used was changed to 50 g of a trimethylolpropane ethyloxy-added alcohol (in the above formula (II), p+q+r=5). After the reaction was completed, the remaining acetylene gas was blown off to obtain 207 g of the reaction liquid. Then the reaction solution was extracted with ether, washed with water, and distilled off to obtain 50 g (yield 82%) of the multifunctional vinyl ether of the present invention (in the above formula (I), l+m+n=5).

Embodiment 3

[0038] The raw material used was changed to 50 g of trimethylolpropane ethyloxy-added alcohol (in the above formula (II), p+q+r=6), and the reaction was carried out in the same manner as in Example 1 . After the reaction was completed, the remaining acetylene gas was blown off to obtain 207 g of the reaction liquid. Then, the reaction solution was extracted with ether, washed with water, and distilled off to obtain 52 g (yield 87%) of the multifunctional vinyl ether of the present invention (in the above formula (I), l+m+n=6).

Abstract

The multifunctional vinyl ether represented by formula (I) below produces little skin irritation, is low in odor, has excellent polymerization initiator solubility and curability and is not readily affected by oxygen during curing. Additionally, a resin composition containing said multifunctional vinyl ether can be used in many fields, such as for inks, coating materials, adhesives and resists, since it satisfactorily dissolves polymerization initiators and has excellent curability. l, m and n in the formula (I) are integers that satisfy the relationship l + m + n > 3.

Description

technical field [0001] The present invention relates to a polyfunctional vinyl ether having low skin irritation, low odor, and excellent solubility of a polymerization initiator. The present invention also relates to a polyfunctional vinyl ether which is less susceptible to the influence of oxygen during polymerization and has excellent curability. Background technique [0002] Currently, acrylic compounds are generally used as the main ingredient of resin compositions in many fields such as inks, paints, adhesives, and resists. However, when an acrylic compound is used as the main ingredient, there are problems in handling such as skin irritation, odor, and curing inhibition by oxygen. In recent years, the performance requirements for resins have gradually increased, and acrylic compounds have been unable to fully meet the needs. On the other hand, vinyl ether compounds have low skin irritation and low odor, exhibit fast curing properties in cationic polymerization, and r...
