- Light stabilization of poly(vinyl butyral) [PVB]
- Light stabilization of poly(vinyl butyral) [PVB]. (Ciba-Geigy A.In this study， 70198-29-7 and 2082-79-3 are also used.-G., Basel, Switz.). Res. Discl., 271, 673 (English) 1986. CODEN: RSDSBB. ISSN: 0374-4353. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) Hindered amine light stabilizers (HALS), e.g. bis(2,2,6,6-tetramethylpiperidyl)sebacate [52829-07-9], or combinations of HALS with UV-absorbers, provide excellent light stability to poly(vinyl butyrals). Similar effects can be achieved by adding ternary blends of HALS, UV-absorbers, antioxidants, and(or) phosphites. The preferred stabilizer concn. is 0.1-1.0%. .

Thus, II film contg. 0.15 phr bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate (III) [52829-07-9] and 0.35 phr I lasted 420 h to failure in Fade-O-Meter exposure compared to 327 h for II contg. only 0.15 phr III and 73 h for the control contg. no light stabilizer. I alone had no stabilizing effect on II. .
