Solid, rapid-setting, rigid polyurethanes. Olstowski, Franciszek (Dow Chemical Co., USA). U.S. US 3983068 28 Sep 1976, 8 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08K005-06. NCL: 260033200R. APPLICATION: US 72-221784 28 Jan 1972. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Compns. which would rapidly set to give solid, rigid polyurethanes without the use of a catalyst comprised an amine-initiated polyether polyol, e.g. triethanolamine [102-71-6], an org. arom. polyisocyanate, e.g. toluene diisocyanate (I) [26471-62-5], and a liq. modifier compd. having a b.p. >150.degree., e.g. trichlorobenzene (II) [12002-48-1]. Thus, 26 g of the reaction product of aminoethanolamine [109-84-2] and propylene oxide [75-56-9] and 30 g II were blended, and 30 g I was rapidly blended into the mixt. and immediately poured into a polyethylene mold or a Mylar tray. The compn. 24356-31-8 and 12002-48-1 which are cas registry numbers of substances are two of reagents here. solidified in 15 sec as compared to 25 sec for a similar compn. not contg. II. Also, the compn. not contg. II swelled, cracked, distorted, and formed gross fissures or cracks. .

DOCUMENT TYPE: Conference CA Section: 5 (Agrochemicals) Spraying 2-4-year-old apples with 0.1-0.4% Alar [1596-84-5] or 0.1-0.4 hydroxyethylhydrazine [109-84-2] increased the foliar chlorophyll and bound water content, and decreased the free water content, inhibited shoot growth and stimulated shoot ripening before winter. CCC [999-81-5] was less effective. .
