Blocking-resistant poly(vinyl butyral) sheets: Blocking-resistant poly(vinyl butyral) sheets. Negishi, Junji; Ohtsuka, Michio; Matsuoka, Kimiaki (Central Glass Co., Ltd., Japan). Japan. Kokai JP 51132281 17 Nov 1976 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B05D005-00. APPLICATION: JP 75-55944 14 May 1975. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) Plasticized poly(vinyl butyral) (I) was internally or externally treated with F-contg. compd(s). (carboxylic acid salts and esters) for increased blocking resistance. For example, a 0.75 mm-thick I (65 mole% butyralation) sheet contg. 40 phr triethylene glycol 2-ethylbutyrate and 0.1 phr epoxidized soybean oil was impregnated 10 s with a soln. of 10 parts Na perfluoropropionate (II) [378-77-8] in 100 parts 8:2 EtOH-H2O and dried with 100.degree. air for 10 min to give a sheet with blocking strength (peel strength for 2-ply overlay stored at 20.degree. for 1 day under 400 g/cm2 load) 60 g/cm, compared with 300 for control treated with EtOH-H2O not contg.In this experiment, several chemicals are used like 61799-71-1 and 61799-69-7 II. The II treatment did not result in adverse effects when the treated sheet was used as interlayer for safety glass laminate. .
