Definitions
- It relates to a process for producing acrylic syrup and acrylic syrup.
- Acrylic syrup has transparency, and the cured product cured thereon is easy to control adhesion to various substrates, and is used in various applications such as adhesive sheets, adhesive films, protective coatings, foams, and adhesives.
- Polymerization methods for producing such acrylic syrups include, for example, solution polymerization, emulsion polymerization, and, in the case of solution polymerization, an organic solvent may remain in the acrylic syrup to cause odor, fire, explosion, and the like. If it is removed by evaporation in the middle, it causes air pollution, which is harmful to the environment.
- organic solvents are not used, but the polymers may not be used as they are, but additives such as neutralizers, wetting agents, thickeners, and fungicides should be added in a large amount. Since a large amount of water is used in the process of washing the reactor is generated a lot of waste water.
- bulk polymerization can be used for eco-friendliness, high yield, and economic efficiency.
- Such bulk polymerization includes thermal thermal polymerization or bulk photopolymerization initiated by light.
- the reaction rate is high and the productivity is high.
- the aforementioned molecular weight regulators remain in the prepared acrylic syrup, and remain even after the acrylic syrup is applied to the product as an adhesive film, a protective coating or a foam, so that the molecular weight regulator having fluidity moves to the surface.
