[0169]

[0170] The preparation method of the acrylic polymer composition of the present invention is not particularly limited, and a method of mixing an acrylic polymer and a polyfunctional organic compound having a urea group together with various compounding agents added as necessary is mentioned.

[0171] The mixing method is not particularly limited, and examples thereof include a method of kneading using a kneading machine such as a roll mill, an internal mixer, a kneader, a Banbury mixer, or a screw kneader. In addition, mixing can be performed in a solvent.

[0172] In addition, in the case of compounding a crosslinking agent, it can be prepared as follows: each component except the crosslinking agent and a crosslinking auxiliary agent unstable to heat, etc., can be prepared by using a Banbury mixer or a Brabender mixer. , internal mixer, kneader and other mixers for mixing, transfer to the roller mill, add cross-linking agent, cross-linking aids that are unstable wh...

Embodiment

[0180] Hereinafter, an Example and a comparative example are given, and this invention is demonstrated more concretely. In addition, unless otherwise specified, "parts" in each example are based on weight.

[0181] Various physical properties were evaluated according to the following methods.

[0182] [Measurement of half-life of polyfunctional organic compound having urea group]

[0183] The half-life of the polyfunctional organic compound having a urea group was heated using a thermogravimetric differential thermal simultaneous measurement device ("TG / DTA7200", manufactured by SII Co., Ltd.) according to the following temperature rise program, and the heating temperature of the measurement device was set at 180°C Thereafter, the weight loss at the time when the temperature of the sample was stabilized at 190° C. was measured, and the time until the weight was half was obtained, which was regarded as the half-life of the polyfunctional organic compound having a urea group. ...

Synthetic example 1

[0195] [Synthesis Example 1: Synthesis of Acrylic Polymer]

[0196] Add 200 parts of water, 3 parts of sodium lauryl sulfate, 100 parts of ethyl acrylate in the polymerization reactor with thermometer, stirring device, nitrogen introduction pipe and decompression device, and reuse degassing and decompression After nitrogen replacement and full removal of oxygen, add 0.002 parts of sodium formaldehyde sulfoxylate and 0.005 parts of cumene hydroperoxide to initiate emulsion polymerization at normal pressure and temperature, and continue the reaction until the polymerization conversion rate reaches 95%. Add The polymerization terminator terminates polymerization. Then, the obtained emulsion polymerization solution was coagulated in an aqueous magnesium sulfate solution, washed with water, and dried to obtain a rubbery acrylic polymer (polyethyl acrylate).

Abstract

Provided is an acrylic polymer composition that contains an acrylic polymer and a polyfunctional organic compound having a urea group. When the acrylic polymer composition is heated under the condition of being in air at 190 DEG C for 144 hours, the rate of decrease in the molecular weight of the acrylic polymer is less than 50%.

Description

technical field [0001] The present invention relates to an acrylic polymer composition, and relates to an acrylic polymer composition capable of effectively preventing thermal deterioration due to heat. Background technique [0002] With the development of petrochemistry, polymers composed of organic compounds have contributed to the development of human beings in various forms such as plastics, rubber, fibers, and films. These can be used in various environments depending on the application, and therefore improvements are being made so as to enable long-term use by imparting durability in assumed environments. For example, plastics that can be used outdoors are being developed with UV resistance, and rubber that can function in extremely cold regions is being developed with cold resistance. [0003] On the other hand, internal combustion engines represented by engines, whose usage is increasing with the development of the industry, require lubricating oil and generate a la...
