摘要:
A radical polymerization initiator comprising as an active ingredient a hydroperoxide of disproportionated or hydrogenated rosin acid or its alkali metal or ammonium salt.The initiator is prepared by contacting disproportionated or hydrogenated rosin acid or its alkali metal or ammonium salt with molecular oxygen in water or an organic solvent at a temperature of 0.degree. to 150.degree.C. to form its hydroperoxide.
