Synthetic example 1

[0083] (Synthesis of dipentaerythritol 2EO adduct acrylate)

[0084] 254 g (1.0 mol) of dipentaerythritol (manufactured by Koei Chemical Company, OH value 1324), 127 g of toluene and 0.3 g of KOH were put into an autoclave having a volume of 1 L and equipped with a stirrer, heated to 90° C. and stirred, to to obtain a suspension. Next, it was heated to 130° C., and 132 g (3 mol) of ethylene oxide was gradually introduced into the autoclave and reacted. With the introduction of ethylene oxide, the internal temperature of the autoclave increased. It was cooled as necessary to keep the reaction temperature below 140°C. After the reaction, it was depressurized at 140° C. under a mercury column of 10 mmHg or less, thereby removing excess ethylene oxide and by-product ethylene glycol polymer. Subsequently, it was neutralized with acetic acid to obtain an adjusted pH of 6-7. The dipentaerythritol 2EO adduct obtained (average 2 mol of added ethylene oxide—the same applies below) h...

[0096] (Synthesis of dipentaerythritol 4EO adduct acrylate)

[0097] 254 g (1.0 mol) of dipentaerythritol (manufactured by Koei Chemical Company, OH value 1324), 127 g of toluene and 0.3 g of KOH were put into an autoclave having a volume of 1 L and equipped with a stirrer, heated to 90° C. and stirred, to to obtain a suspension. Next, it was heated to 130° C., and 220 g (5 mol) of ethylene oxide was gradually introduced into the autoclave and reacted. With the introduction of ethylene oxide, the internal temperature of the autoclave increased. It was cooled as necessary to keep the reaction temperature below 140°C. After the reaction, it was decompressed at 140° C. to a mercury column of 10 mmHg or less, thereby removing excess ethylene oxide and by-product ethylene glycol polymer. Subsequently, it was neutralized with acetic acid to obtain an adjusted pH of 6-7. The OH value of the obtained dipentaerythritol 4EO adduct was 765.

Abstract

The present invention provides a polyurethane acrylic and a reactive composition containing polyurethane acrylic. In each polyurethane acrylic and reactive composition, such as the problem of poor manipulation performance of the reactive composition andThe problem of increased curing and contraction rates of reactive compositions can be improved, and each polyurethane acrylic and reactive composition can improve curing performance and surface hardness.A polyurethane acrylics produced by the structure of oxide (I) and the structure represented by a pseudo -type (i) and the structure represented by the general (ii) structure are modified by the structure of oxide.In the formula, the average value of the average aggregation of the addition of the addition of the addition of the addition of the bonus (AO) is greater than 0 and does not exceed 5, the average value of M is greater than 0 and no more than 6.The average value of the larger and less than 6 is 0 to 6, which contains 0 and 6, and the total of M, N and O is 6, and R2 represents hydrogen atoms or methyl.

Description

technical field [0001] The invention relates to a reaction composition containing urethane acrylate and the urethane acrylate used in the reaction composition. Specifically, the present invention relates to a reactive composition exhibiting high pencil hardness, scratch resistance, abrasion resistance, adhesion to substrates, transparency and stain resistance after curing, and for use in The reaction composition is a urethane acrylate. Background technique [0002] Reactive compositions containing urethane acrylates can be formulated with outstanding toughness, flexibility, scratch resistance, weatherability, chemical resistance, and other characteristics. In addition, the composition has a feature that it can be cured in a short period of time by heating or irradiation using active energy rays, and can be advantageously used for optical use elements, photoresist compositions, hard coating compositions and for Production of Inkjet Ink Compositions. [0003] Recently, in m...
