An aromatic shower sachet is a personal hygiene and aromatherapy device used to diffuse pleasant and therapeutic scents throughout a shower area when exposed to water or steam. The aromatic shower sachet utilizes a permeable enclosure containing a quantity of aromatic compound, a quantity of absorbent starch, a quantity of reactive base, and a quantity of acid catalyst homogenously mixed into water-reactive mixture. The water-reactive mixture is retained within the permeable enclosure such that water or water vapor may penetrate the permeable enclosure. The water reacts on-contact with the water-reactive mixture, releasing fragrances through the permeable enclosure.

It is an object of the present invention to provide a method for producing a terminal-modified polybutadiene or terminal-modified hydrogenated polybutadiene that does not become colored or white and turbid, without using an organotin compound. The production method of the present invention includes reacting an acrylate or methacrylate represented by formula (I), a diisocyanate compound represented by formula (II), and a polybutadiene or hydrogenated polybutadiene having a hydroxyl group at a polymer terminal, represented by formula (III), in the presence of at least one selected from an organoaluminum compound and an organozinc compound (with the proviso that zinc naphthenate is excluded). ##STR00001##
