Description

The present invention relates to a fine particle adsorption preventing polymer.

Fine particles suspended in the air, such as pollen, viruses, house dust, fine particulate matter (PM2.5), etc., are substances that may have undesired effects on the human body. For example, with regard to pollen, the number of people who develop pollinosis is increasing year by year in Japan. At present, no reliable radical therapy has been established for pollinosis. A common hay fever control is to reduce the chance and amount of pollen exposure. It is also desired to reduce the chances and amount of contact with fine particles such as viruses and house dust from the viewpoint of preventing the effects on the human body and the onset of allergies. Furthermore, for soot and smoke emitted from factories, automobiles, ships, aircraft, volcanoes and soil, and gaseous air pollutants such as sulfur oxides (SOx), nitrogen oxides (NOx), and volatile organic compounds (VOC). Since dust such as derived fine particulate matter causes respiratory diseases such as asthma and allergic diseases, it is desired to reduce the contact opportunity and amount. As such measures, for example, it is widely practiced to wear a mask, glasses, and a hat when going out to reduce contact with fine particles such as pollen, viruses, house dust, and fine particulate matter. However, it may be difficult to wear them, for example, while eating or sleeping, and further, wearing them may obstruct the view. Therefore, there is a strong demand for a means capable of reducing contact with fine particles such as pollen, viruses, house dust, and fine particulate matter without such problems.

Among the above polymerization methods, considering the use as a fine particle adsorption inhibitor, it is more preferable to prepare in advance by a solution polymerization method in which copolymerization is carried out in water, a hydrophilic solvent, or a mixture thereof.

As used herein, the hydrophilic solvent refers to an organic solvent having a solubility in water of 10 g / 100 g (25 ° C.) or more of water.

The amine value represents a solid amine value, and can be measured by a known method described in JIS K 7237 as an example.

The acid value and amine value of the polymer (A) may be determined from the structure of each monomer constituting the polymer (A) and the ratio of the amount of each monomer used. Specifically, the acid value is the theoretical mg number of KOH required to neutralize the acid group in the polymer (A), and the amine value is to neutralize the amine in the polymer (A). It may be obtained from the required theoretical mg number of KOH. If the acid value and amine value of each monomer used in producing the polymer (A) are known, known values may be used. In the present specification, when the polymer (A) has an amphoteric monomer containing both an acid group and an amine group in a monomer such as a betaine monomer, the acid group or amine group of the amphoteric monomer has an acid value or an amine.
