Reaction of isocyanates with southern pine wood to improve dimensional stability and decay resistance: Reaction of isocyanates with southern pine wood to improve dimensional stability and decay resistance. Ellis, W. Dale; Rowell, Roger M. (Forest Prod. Lab., U.S. Dep. Agric., Madison, WI 53705, USA). Wood Fiber Sci., 16(3), 349-56 (English) 1984. CODEN: WFSCD4. ISSN: 0735-6161. DOCUMENT TYPE: Journal CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 10 Of the isocyanates, Ph isocyanate (I) [103-71-9], p-tolyl isocyanate [622-58-2], 1,6-diisocyanatohexane (II) [822-06-0], isophorone diisocyanate [4098-71-9], and tolylene 2,4-diisocyanate (III) [584-84-9] formed mostly non-bonded polymers in the pinewood voids when 5% or less catalyst (Et3N) or solvent (DMF) were present, so that these polymers did not increase the dimensional stability (DS) or decay resistance to Gloeophyllum trabeum of wood. Et isocyanate [109-90-0], Pr isocyanate [110-78-1], and Bu isocyanate (IV) [111-36-4] reacted with OH groups in wood in the presence or absence of catalyst or solvent gave modified wood which had 30-50% better DS than unmodified one, high resistance to decay and lost 4% or less wt. in std. solid-block-test. The reaction of I, II, III and IV with wood in the presence of 35% DMF gave product with increased wt., vol., and DS, and IV-modified wood at 30-35% wt. gain was 70% more dimensionally stable than unmodified one and lost 2% wt. in std. soil-block test.

Isocyanato prepolymers of diisocyanates containing differently reactive NCO-groups: Isocyanato prepolymers of diisocyanates containing differently reactive NCO-groups. Lorenz, O.; Decker, H.; Rose, G. (Fachhochsch. Aachen, Aachen D-5100, Fed. Rep. Ger.). Angew. Makromol. Chem., 122, 83-99 (German) 1984. CODEN: ANMCBO. ISSN: 0003-3146. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 22, 67 Two methods are described for detg. the ratio (g) of the rate consts. for urethane formation by isocyanates having 2 NCO groups of differing reactivity. In the reaction of hexamethylene diisocyanate [822-06-0] or isophorone diisocyanate [4098-71-9] with excess BuOH [71-36-3], the consumption of both NCO groups follows 1st-order kinetics. The g so detd. is 1.0 and 5.1-4.4, resp., at 40-65°. In the reaction of excess diisocyanate with macrodiols, e.g. polytetramethylene glycol [25190-06-1], g can be estd. from NCO consumption provided that when g is not 1, the reaction is 1st-order for both NCO groups. Under these conditions, and knowing g, product compn., diisocyanates singly or doubly bonded, and the type of NCO end groups on prepolymers can be calcd.
