実験手順: The base particles, along with helium gas, were cooled and introduced through the particle intake 4 into the vapor atmosphere of sebacoyl chloride in the mixing section 22. Next, in the mixing section 22, the vapor of sebacoyl chloride was cooled, and the introduced base particles were exposed thereto for 2 minutes. Consequently, a polymerization reaction, using as a catalyst triethylamine contained in the base particles, took place on the surface of the base particles between sebacoyl chloride and ethylene glycol, forming a film of ethylene glycol-sebacoyl chloride co-polymer. The base particles, along with helium gas, were cooled Consequently, a polymerization reaction

実験手順: A solution of 17.10 parts of 1,2,2,6,6-pentamethylpiperidin-4-ol in 50 parts of dry benzene was stirred at 15°-20° C. whilst adding 6.0 parts of sebacoyl chloride dropwise over 15 minutes. The mixture was stirred for a further 12 hours at room temperature after which the 1,2,2,6,6-pentamethylpiperidin-4-ol hydrochloride formed during the reaction was filtered off. The benzene was removed by distillation under reduced pressure to give a yellow oil, which was distilled under reduced pressure to give bis-(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate as a colourless oil having a boiling point of 218°-20° C. at 0.4 mm of Hg and the following elemental analysis by weight: formed during the reaction was filtered off The benzene was removed by distillation under reduced pressure to give a yellow oil, which was distilled under reduced pressure
