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

A method for manufacturing a plastic lens, comprising:

• a step of preparing a polymerizable composition for an optical material by mixing an allyl Patent carbonate compound (A) including two or more allyloxycarbonyl groups at a terminal which is represented by General Formula (1) with a radical polymerization initiator (B);
• and
• a step of forming a lens base material by cast polymerization of the polymerizable composition for an optical material,
• wherein the radical polymerization initiator (B) includes at least one kind of radical polymerization initiator (B1) which is a peroxyester-based radical polymerization initiator in which a radical residual ratio after 5 hours at 50° C. is 10% or more and 90% or less and which has an alkyl group having 5 or more carbon atoms and including a tertiary carbon atom directly connected to an O—O bond, and
• a radical polymerization initiator (B2) in which a residual radical ratio after 5 hours at 95° C. is 10% or more and 90% or less and which is at least one kind selected from the group consisting of a peroxyester-based radical polymerization initiator, a peroxyketal-based radical polymerization initiator, and a peroxymonocarbonate-based radical polymerization initiator,
• wherein, in General Formula (1), R1 represents a chained or branched divalent to 20 valent group derived from an 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.
