| titleOfInvention | Curable composition and production of prepolymer using therefor |
| abstract | PURPOSE: To obtain the subject composition useful as optical materials or a sealing agent, etc., having excellent storing stability by adding radical polymerization initiator to monomeric components comprising a specific prepolymer and a polymerizable monomer copolymerizable with said prepolymer. n CONSTITUTION: A (meth)acryloyl group of a compound expressed by formula I (R 1 and R 2 are H or methyl; m and n are 1-5) is subjected to addition polymerization together with mercapto functional group of a polythiol expressed by formula II (R is organic group composed of polyfunctional aliphatic or aromatic hydrocarbon; n is integer of ≥2) in an equivalent ratio of 0.02-1.01 preferably in the presence of a basic catalyst such as triphenylphosphine to obtain a prepolymer having a polythiol skeleton. Next, a radical polymerization initiator, preferably in an amount of 0.01-10 mol%, is added to monomer components composed of 30 wt.% said prepolymer and 70 wt.% polymerizable monomer copolymerizable with said prepolymer to afford the aimed composition. n COPYRIGHT: (C)1991,JPO&Japio |
