Embodiment 1

[0664] (Example 1: Measurement of the illuminance of ultraviolet rays that generate a predetermined strain)

[0665] The illuminance of ultraviolet light for producing a polymer having a predetermined strain is determined by the following procedure.

[0666] [Derivation of strain-illuminance relationship]

[0667] 1) Provide the starting material monomer

[0668] For each specific example after Example 2, an appropriate monomer is selected. For example, in the case of the (meth)acrylic polymer of Example 2, by mixing 7.03 g of ethyl acrylate, 0.17 g of diethylene glycol dimethacrylate, and 2,4,6-trimethacrylate as a polymerization initiator, Toluyldiphenylphosphine oxide [manufactured by BASF Corporation, trade name: Irgacure TPO] 0.0042 g was provided as a monomer component containing a polymerization initiator.

[0669] 2) The starting material monomer is irradiated with ultraviolet rays of a specific intensity to polymerize

[0670] After obtaining an appropriate monome...

Embodiment 2

[0693] Acrylic Resin(1)

[0694] By mixing 7.03 g of ethyl acrylate, 0.17 g of diethylene glycol dimethacrylate, and 2,4,6-trimethylbenzoyldiphenylphosphine oxide [manufactured by BASF Corporation, trade name: Irgacure TPO] 0.0042 g to obtain a monomer component containing a polymerization initiator.

[0695] The monomer component obtained above is poured into a transparent glass mold with a release film (length: 100mm, width: 100mm, depth: 0.3mm) so that the amount of radiation is 0.5 to 50mW / cm 2 The monomer component was irradiated with ultraviolet rays in a manner to polymerize the monomer component in bulk, thereby obtaining a (meth)acrylic elastomer. The measurement results are shown in Table 1 below.

Embodiment 3

[0697] Acrylic Resin(2)

[0698] By mixing 30.01 g of ethyl acrylate, 0.35 g of 2-hydroxyethyl acrylate, and 2,4,6-trimethylbenzoyldiphenylphosphine oxide [manufactured by BASF, trade name: Irgacure TPO] as a polymerization initiator 0.038 g to obtain a monomer component containing a polymerization initiator.

[0699] The monomer component obtained above is poured into a transparent glass mold with a mold release film (length: 100mm, width: 100mm, depth: 2mm) so that the irradiation dose becomes 0.5 to 50mW / cm 2 The monomer component was irradiated with ultraviolet rays in a manner to polymerize the monomer component in bulk, thereby obtaining a (meth)acrylic elastomer. The measurement results are shown in Table 2 below.

Abstract

The purpose of the present invention is to provide a method for manufacturing a polymer having a desired strain. Provided is a method for manufacturing a polymer having a desired strain, said method comprising: a step for polymerizing one or more kinds of starting monomers by irradiating with ultraviolet rays having such an illuminance as to generate the desired strain; and, if required, a step for measuring the strain of the polymers thus formed and selecting a polymer having the desired strain. In one embodiment, provided is a method for determining the illuminance of ultraviolet rays for manufacturing a polymer having a desired strain.

Description

technical field [0001] The present invention relates to an improved method for producing resins such as (meth)acrylic resins. More specifically, the present invention relates to a method for producing a resin (for example, a (meth)acrylic resin) in which strain is controlled by controlling exposure illuminance. Involves less strained resins obtained by low light exposure. [0002] The invention also relates to a strain-adjustable material, such as a (meth)acrylic dielectric material. The present invention also relates to materials that can be expected to be used in, for example, sensors, power generating elements, speakers, microphones, mufflers, transducers, artificial muscles, small pumps, medical devices, etc. used in actuators, industrial robots, etc., such as (meth)acrylic dielectric material. Background technique [0003] (Meth)acrylic resins are used as various materials because of their high transparency and impact resistance, and their ease of thermoplastic moldi...
