Hardening of urea-formaldehyde binders

Hardening of urea-formaldehyde binders. Kinastowski, Stefan; Morze, Zbigniew; Cendrowska, Anna (Akademia Rolnicza, Pol.). Pol. PL 85670 15 Oct 1976, 3 pp. (Polish). (Poland). CODEN: POXXA7. CLASS: IC: C08G051-80. APPLICATION: PL 74-168910 18 Feb 1974. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) The hardening time of urea-HCHO resins [9011-05-6] is decreased by 30-60% by adding, in addn. to NH4Cl, thermally unstable org. acids such as malonic [141-82-2], acetoacetic [541-50-4], vinylacetic [625-38-7], nitroacetic [625-75-2], trinitrobenzoic [129-66-8], or a-halocarboxylic acids. Free org. acids catalyze the crosslinking at relatively low temps. and are decompd. to catalytically inactive products at higher temps.

A new type of induced decomposition

A new type of induced decomposition. IV. Pyrolysis of t-butyl peroxy-3-butenoate in the gas phase. Ochiai, Tameichi; Yoshida, Masayuki; Simamura, Osamu (Fac. Sci., Tokyo Univ., Tokyo, Japan). Bull. Chem. Soc. Jpn., 49(9), 2641-2 (English) 1976. CODEN: BCSJA8. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Tert-Bu peroxy-3-butenoate decompd. in the gas phase at 115.degree. 75-91-2 and 625-38-7 which are cas registry numbers of chemicals are mentioned. to give CO2, 1-butene, acetone, 1,5-hexadiene, methane, and ethane. Expts. with iodine, an effective radical scavenger, indicate the operation of induced decompn. The mechanism of the formation of 1-butene and 1,5-hexadiene involves an addn.-elimination mechanism. .
