    摘要: The present invention discloses a method for producing plastic optical member comprising a core region and a clad region. The method comprises carrying out polymerization of a polymerizable monomer, thereby obtaining an area corresponding to the core region. The Polymerization is carried out in the presence of a polymerization initiator having a ten-hour, half-life decomposition temperature T h (°C) (T b - 20 ≦ T h ; T b is the boiling point (°C) of the polymerizable monomer), at an initial polymerization temperature T 1 (°C) (T b -10 ≦ T 1 ≦ T g ; T g is the glass transition point (°C) of the polymer made of the polymerizable monomer) , for a period which is equal to or longer than 10% of the half-life of the polymerization initiator at T 1 ; and further carried out at an elevated temperature T 2 (°C) (T g ≦ T 2 and T 1 2 ) .
