Embodiment 1

[0132] The components of Example 1 were taken in parts by mass shown in Table 1, and were mixed at room temperature (25° C.) for 60 minutes using a mixer (device name Tornado high output power type PM-202 (manufactured by AS ONE Co., Ltd.), rotating speed: 100 rpm). Minutes, a photocurable resin composition was prepared, and various physical properties were measured as follows. It should be noted that the detailed preparation amounts are in accordance with Table 1, and all numerical values ​​are expressed in parts by mass.

Embodiment 2～9 and comparative example 1～7

[0134] The photocurable resin compositions of Examples 2 to 9 and Comparative Examples 1 to 7 were also prepared in the same manner as in Example 1 using the components taken in parts by mass shown in Table 1 and Table 2, and various physical properties were measured. . It should be noted that the detailed preparation amounts are in accordance with Table 1 and Table 2, and all numerical values ​​are expressed in parts by mass.

[0136] Production of polyisobutylene polymer (a1) having acryloyloxyethoxyphenyl group

[0137] After substituting nitrogen in the container of the 5 L separable flask, 200 mL of n-hexane and 2000 mL of butyl chloride were added, and cooled to -70°C while stirring under a nitrogen atmosphere. Next, 840 mL (9 mol) of isobutene, 12 g (0.05 mol) of p-dicumyl chloride, and 1.1 g (0.012 mol) of 2-picoline were added. After the reaction mixture was cooled to -70°C, 5.0 mL (0.05 mol) of titanium tetrachloride was added to start polymerization. ...

Abstract

The present invention addresses the problem of providing a photocurable resin composition that exhibits excellent surface curability and deep curability upon irradiation with active energy rays such as ultraviolet rays, while maintaining the sealing properties thereof. Specifically, the present invention provides a photocurable resin composition comprising the following components (A) to (C). Component (A): a polymer having at least one (meth)acryloyl group and having a polyisobutylene backbone containing a -[CH2C(CH3)2]- unit. Component (B): a photoradical polymerization initiator. Component(C): a triarylphosphine derivative or a xanthone derivative.

Description

technical field [0001] The present invention relates to a photocurable resin composition that maintains sealing properties and is excellent in surface curability and deep curability by irradiation of active energy rays such as ultraviolet rays. Background technique [0002] In recent years, fuel cells have attracted attention as a new energy system for automobiles and households. A fuel cell is a power generation device that generates electricity by chemically reacting hydrogen and oxygen. In addition, the fuel cell is a next-generation clean power generation device because of its high energy efficiency during power generation, and the generation of water through the reaction of hydrogen and oxygen. There are four types of fuel cells: solid polymer fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, and solid oxide fuel cells. Among them, solid polymer fuel cells have a relatively low operating temperature (80 °C) and high power generation efficiency, it i...
