SOLVENTLESS LIQUID ACRYLIC RESIN COMPOSITION AND METHOD FOR PRODUCING SOLVENTLESS LIQUID ACRYLIC RESIN COMPOSITION
PROBLEM TO BE SOLVED: To provide a solventless liquid acrylic resin composition which is useful as a fixing material of gravel or aggregate, is excellent in weather resistance and adhesiveness, has adequate flowability, and is excellent in workability and has little influence on environment because of containing no volatile organic solvent.SOLUTION: A solventless liquid acrylic resin composition contains no water and volatile organic solvent as a solvent, contains a reactant obtained by copolymerization of component A containing at least a (meth)acrylate monomer having no reactive functional group and component B being a hydrolyzable alkoxysilyl group-containing monomer copolymerizable with the component A, in the presence of a chain transfer agent, in a liquid compound (component C) which has no copolymerizability with the component A, has a boiling point of 150°C or higher and has viscosity at 25°C of 50,000 mPa s or less, when the total of the component A and the component B is 100 pts.mass, an amount of the component C is 10 to 900 pts.mass and R viscosity calculated by viscosity×viscosity ratio is 100 mPa s or more and less than 20,000 mPa s.SELECTED DRAWING: None
【課題】砂利或いは骨材の固定材料として有用な、耐候性及び接着性に優れ、適度な流動性を有し、揮発性の有機溶剤を含有しないため、作業性に優れ、環境への影響が少ない無溶剤液状アクリル樹脂組成物の提供。【解決手段】水及び揮発性有機溶剤を溶媒として含まず、反応性官能基を有さない（メタ）アクリル酸アルキルエステル単量体を少なくとも含むＡ成分と、該Ａ成分と共重合可能な加水分解性アルコキシシリル基含有単量体であるＢ成分とを、連鎖移動剤の存在下、Ａ成分と共重合性を持たない、沸点が１５０℃以上で、且つ、２５℃での粘度が５００００ｍＰａ・ｓ以下である液状化合物（Ｃ成分）中で共重合してなる反応物を含み、Ａ成分とＢ成分との合計量を１００質量部とした場合に、Ｃ成分の量が１０〜９００質量部であり、且つ、粘度×粘度比で算出されるＲ粘度が、１００ｍＰａ・ｓ以上、２００００ｍＰａ・ｓ未満である無溶剤液状アクリル樹脂組成物。【選択図】なし
