【０００６】
【課題を解決するための手段】
本発明は、粘度平均分子量１００万以上の線状メタクリル酸メチル系重合体０．５〜３．５重量部、粘度平均分子量５〜３０万のメタクリル酸メチル系重合体５〜２５重量部およびメタクリル酸メチル系モノマー７１．５〜９４．５重量部からなるシロップ１００重量部に、メタクリル酸メチル系モノマーと共重合可能な多官能性モノマー０．１〜０．５重量部および連鎖移動剤０．０１〜０．３０重量部を添加してなるシロップを、セルに注入して重合させるサニタリー用メタクリル樹脂板の製造方法である。[0006]
[Means for Solving the Problems]
The present invention comprises 0.5 to 3.5 parts by weight of a linear methyl methacrylate polymer having a viscosity average molecular weight of 1,000,000 or more, 5 to 25 parts by weight of a methyl methacrylate polymer having a viscosity average molecular weight of 5 to 300,000 and methacryl 100 parts by weight of a syrup consisting of 71.5 to 94.5 parts by weight of a methyl acid based monomer, 0.1 to 0.5 parts by weight of a polyfunctional monomer copolymerizable with the methyl methacrylate based monomer and a chain transfer agent 0. It is a manufacturing method of the methacrylic resin board for sanitary products which injects into a cell and polymerizes the syrup which adds 01-0.30 weight part.
【００１４】
該粘度平均分子量１００万以上の線状メタクリル酸メチル系重合体をメタクリル酸メチル系モノマーに溶解する方法は、従来公知の方法でよい。例えば、メタクリル酸メチルモノマーおよび、メタクリル酸メチルモノマーと共重合可能なコモノマーを含有するモノマー混合物にラジカル重合開始剤を添加、加熱してその一部を部分重合することによってメタクリル酸メチルモノマーあるいは、メタクリル酸メチルモノマーと共重合可能なコモノマー溶液として得られる。それをそのまま、あるいは希釈して所定の濃度にすれば良い。また、懸濁重合、乳化重合等により得られる該粘度平均分子量１００万以上の線状メタクリル酸メチル系重合体を該メタクリル酸メチル系モノマーに溶解しても良い。[0014]
The method of dissolving the linear methyl methacrylate based polymer having a viscosity average molecular weight of 1,000,000 or more in a methyl methacrylate based monomer may be a conventionally known method. For example, a radical polymerization initiator is added to a monomer mixture containing a methyl methacrylate monomer and a comonomer copolymerizable with the methyl methacrylate monomer, and the methyl methacrylate monomer or methacrylate is obtained by partially heating a portion thereof by heating. It is obtained as a comonomer solution copolymerizable with the acid methyl monomer. It may be diluted to a predetermined concentration as it is. The linear methyl methacrylate polymer having a viscosity average molecular weight of 1,000,000 or more obtained by suspension polymerization, emulsion polymerization or the like may be dissolved in the methyl methacrylate monomer.
