Photochemical preparation of oligopropylene glycols: Photochemical preparation of oligopropylene glycols. Degtyareva, A. A. (IKhVS, USSR). Khim. Tekhnol. (Kiev), (5), 16-18 (Russian) 1984. CODEN: KHMTA6. ISSN: 0368-556X. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Oligomeric polypropylene glycols [9051-51-8] were prepd. by photochem. polymn. of propylene oxide [75-56-9] in the presence of diethylene glycol (I) [111-46-6] and PhSPF6 (II) [57835-99-1] catalyst. A lamp emitting light at 300-500 nm with max. at 360-365 nm was used as the radiation source. The polymn. was proceeded by an induction period of 3-5 min. An increase in the concn. of the catalyst (0.005-0.02 mol/dm3), I concn., light intensity, or temp. (298-303 K) increased the reaction rate. The effect of temp. was attributed to the occurrence of a dark polymn. catalyzed by HPF6 formed in the temp.-independent photolysis of II.

Dry transfer materials: Dry transfer materials. McKie, Peter; Shadbolt, Philip; Hodd, Kenneth (Letraset Ltd., UK). Brit. UK Pat. Appl. GB 2142279 A1 16 Jan 1985, 6 pp. (English). (United Kingdom). CODEN: BAXXDU. CLASS: ICM: B41M003-12. APPLICATION: GB 83-17754 30 Jun 1983. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Dry transfers comprise carrier sheets printed with solventless inks contg. cationically curable org. materials and cationic initiators. The ink is cured by radiation and overcoated with adhesive. Thus, a transfer ink was prepd. by milling epoxy novolak resin DEN 438 [63957-64-2] 23, cycloaliph. epoxy resin CY 179 [25085-98-7] 68, and pigment 1.8 parts and adding 4.5 parts 50% Ph3S+ PF6- [57835-99-1] catalyst and 2.7 parts leveling agent. The ink was screen printed on a polyethylene release sheet, curved by UV light, and coated with an adhesive.
