Definitions
- the present invention includes the following embodiments.
- Two or more reaction raw materials comprising a monomer mixture containing 80 to 100% by weight of methyl methacrylate and 20 to 0% by weight of an acrylic acid alkyl ester, a chain transfer agent, and a radical polymerization initiator
- the shape of the supply port may be the shape of the cut end of the circular tube itself, or may be a shape such that the reaction raw material is widely dispersed on the liquid surface in the reaction tank.
- the complete mixing time ( ⁇ M [hr]) of the tank reactor is equal to the half-life ( ⁇ 1/2 [hr]) of the radical polymerization initiator at the temperature in the tank reactor.
- a time of a numerical value larger than a numerical value preferably a time of a numerical value larger than a numerical value of 1.2 times the half-life. That is, the relationship ⁇ M > ⁇ 1/2 , preferably the relationship ⁇ M > 1.2 ⁇ ⁇ 1/2 is satisfied.
- the complete mixing time is one of indexes indicating the mixing characteristics of the reaction vessel.
- n ⁇ ⁇ M -Re indicating the relationship between n ⁇ ⁇ M (the dimensionless mixing number [n is the number of revolutions of the stirring blade [1 / sec]]) and Re (Reynolds number: an index representing the turbulent state of the liquid) It is obtained from the “curve”.
- the complete mixing time and the n ⁇ ⁇ M -Re curve are described in, for example, Non-Patent Document 2, Patent Document 4, and Patent Document 5.
- the ultraviolet absorber is a compound having an ability to absorb ultraviolet rays.
- the ultraviolet absorber is a compound that is said to have a function of mainly converting light energy into heat energy.
- Examples of the ultraviolet absorber include benzophenones, benzotriazoles, triazines, benzoates, salicylates, cyanoacrylates, succinic anilides, malonic esters, formamidines, and the like. These can be used alone or in combination of two or more.
- benzotriazoles or ultraviolet absorbers having a maximum molar extinction coefficient ⁇ max at a wavelength of 380 to 450 nm of 1200 dm 3 ⁇ mol ⁇ 1 cm ⁇ 1 or less are preferable.
- an ultraviolet absorber having a maximum molar extinction coefficient ⁇ max at a wavelength of 380 to 450 nm of 1200 dm 3 ⁇ mol ⁇ 1 cm ⁇ 1 or less, 2-ethyl-2′-ethoxy-oxalanilide (manufactured by Clariant Japan, Inc .; Trade name Sundeyuboa VSU).
- benzotriazoles are preferably used from the viewpoint of suppressing resin degradation due to ultraviolet irradiation.
- the polymer processing aid is a compound that exhibits an effect on thickness accuracy and thinning when a (meth) acrylic resin composition is molded.
- the polymer processing aid is polymer particles having a particle diameter of 0.05 to 0.5 ⁇ m, which can be usually produced by an emulsion polymerization method.
- the polymer particles may be single layer particles composed of polymers having a single composition ratio and single intrinsic viscosity, or multilayer particles composed of two or more kinds of polymers having different composition ratios or intrinsic viscosities. May be.
- additives may be added at the reaction raw material stage, may be added at the reaction product stage, or may be added at the stage of the (meth) acrylic resin composition obtained after devolatilization. Good.
- the complete mixing time was 45 seconds, the stirring power was 2.6 kW / m 3 , the Reynolds number was 209, the power number was 6, and the dimensionless mixing number was 150.
- P V ⁇ ⁇ ⁇ I ⁇ ⁇ 1/2 was 0.5.
- the rotation speed of the stirring blade was changed to 100 rpm and the polymerization conversion rate was confirmed after 4 hours, it was determined that the polymerization conversion rate could be controlled by the stirring rotation speed because it changed by 2% or more.
