Polymerizable composition for optical material, molded product, optical material, and plastic lens and method for manufacturing same

A polymerizable composition for an optical material, comprising:

• an allyl carbonate compound (A) including two or more terminal allyloxycarbonyl groups which is represented by General Formula (1);
• and
• a radical polymerization initiator (B) including a combination of a radical polymerization initiator (B1) and a radical polymerization initiator (B2),
• wherein the radical polymerization initiator (B1) is a peroxyester-based radical polymerization initiator,
• the radical polymerization initiator (B2) is at least one kind selected from the group consisting of a peroxyester-based radical polymerization initiator and a peroxyketal-based radical polymerization initiator, and
• the radical polymerization initiator (B1) is contained 0.2 parts by weight or more and 0.7 part by weight or less, and the radical polymerization initiator (B2) is contained 0.8 parts by weight or more and 3.0 parts by weight or less, with respect to 100 parts by weight of the allyl carbonate compound (A),
• wherein, in General Formula (1), R1 represents a divalent to 20 valent group derived from a chained or branched aliphatic polyol with 3 to 35 carbon atoms which optionally include a hetero atom, or a divalent to 20 valent group derived from a cycloaliphatic polyol with 5 to 40 carbon atoms which optionally include a hetero atom, n represents an integer of 2 to 20, and R1 does not include an allyloxycarbonyl group,
• wherein the peroxyester-based radical polymerization initiator used as the radical polymerization initiator (B1) includes t-hexylperoxypivalate, t-hexylperoxyneodecanoate, 1,1,3,3-tetramethylbutylperoxyneodecanoate, t-amylperoxyneodecanoate, or t-amylperoxypivalate,
• the peroxyester-based radical polymerization initiator used as the radical polymerization initiator (B2) includes t-butylperoxyisononanoate, t-amylperoxy normal octanoate, or t-amylperoxyisononanoate,
• the peroxyketal-based radical polymerization initiator used as the radical polymerization initiator (B2) includes n-butyl-4,4-di(t-butylperoxy) valerate, 2,2-bis(4,4-di-t-butylperoxycyclohexyl) propane, or 2,2-di(t-butylperoxy) butane.
