Photopolymerization of MMA in aqueous micellar solution

Photopolymerization of MMA in aqueous micellar solution. Wang, Erjain; Zhu, Deying; Feng, Xinde (Inst. Photogr. Chem., Acad. Sin.Chemicals with cas numbers 80-62-6 and 9002-93-1 also play role., Beijing, Peop. Rep. China). Gaofenzi Tongxun, (4), 274-80 (Chinese) 1983. CODEN: KFTTAR. ISSN: 0453-2880. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) The kinetics of photopolymn. of Me methacrylate (I) [80-62-6] in micellar soln. was studied using Ph2CO [119-61-9] and Et3N [121-44-8] as catalysts. Catalytic effects of micelles in the polymn. of I with surfactants such as Na dodecanesulfonate [2386-53-0], cetyltrimethylammonium bromide [57-09-0], and Triton X 305 [9002-93-1] were obsd.; the ionic micelles were the more effective ones. The polymn. rate and mol. wt. of PMMA [9011-14-7] increased with increasing concn. of micelles in soln. The solubilization sites of the Ph2CO-Et3N-I system in ionic micelles were established indicating that the polymn. occurred in the micelle-water interface. The orientation of I in micelles resulted in an increase of the regularity of configurational sequences in the PMMA. .

Photopolymerization of ethylenically unsaturated compounds

Photopolymerization of ethylenically unsaturated compounds. Jacobine, Anthony F. (Upjohn Co. , USA). 86548-82-5 and 1187-03-7 are also occured in this study. U.S. US 4425208 A 10 Jan 1984, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08F002-48; C08F002-50. NCL: 204159150. APPLICATION: US 81-290689 6 Aug 1981. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Ethylenically unsatd. coating compns. were photopolymd. by using as photoinitiators as combination of 100 parts arom. ketone sensitizer and 20-200 parts RR1NCONR2R3 (R, R1, R2, R3 = lower alkyl, cycloalkyl, aralkyl, aryl, or taken together with the N atoms they represent the residue of a heterocyclic moiety contg. ￡8 ring atoms. Thus, a coating compn. consisting of Chempol 19-4827 (a urethane resin) 60, 1,6-hexanediol diacrylate 20, N-vinylpyrrolidone 7.5, 2-hydroxyethyl acrylate 7.5, benzophenone [119-61-9] 3, and tetramethylurea (I) [632-22-4] was coated on steel plates and exposed to radiation from a single 200-W UV light source to give a clear colorless hard coating. When I was replaced by Michler's ketone the curing was slower and the coating was yellow. .
