标 题:Process for the synthesis of a copolyester adhesive resin
发明人：WILSON JOHN R; ROUSEK MARIAN M; MASSEY FRED L
权利人:GOODYEAR TIRE & RUBBER
摘要:Isophthalic acid is commonly utilized as a comonomer in the preparation of copolyester resins which are utilized as solution adhesives. Unfortunately, solutions of such resins frequently become hazy due to the presence of cyclic oligomers. This invention is based upon the unexpected discovery that the presence of protonic acids during the synthesis of the copolyester resins containing isophthalic acid utilizing conventional metallic catalysts results in solutions of the resins in organic solvents being virtually haze free. The subject invention more specifically reveals a process for synthesizing a polyethylene terephthalate/isophthalate/azelate copolyester resin which is particularly useful as a solution adhesive resin, comprising reacting ethylene glycol with a diacid component which is comprised of (a) from about 25 to about 45 mole percent terephthalic acid, (b) from about 10 to about 30 to about 55 mole percent azelaic acid based upon the diacid component; in the presence of at least one metallic catalyst selected from the group consisting of antimony compounds, titanium compounds; manganese compounds, and germanium compounds and in the presence of at least one protonic acid having a pKa of less than about 2.5; wherein the amount of metallic catalyst present is within the rang eof about 130 ppm to about 1500 ppm and wherein the amount of protonic acid present is within the range of about 50 ppm to about 500 ppm, with said amounts being based upon the weight of the copolyester resin produced.

标题:Process for the synthesis of heat-curable silicone resins
发明人：KOERNER GOETZ; PRIESCH MANFRED; RAU HARALD; SCHAMBERG ECKEHARD
权利人:GOLDSCHMIDT AG TH
摘要:The invention relates to a process for heat-curable silicone resins and their synthesis by reacting a low molecular weight alkoxysilane with a low molecular weight polyol with 2 to 6 hydroxyl groups in the molecule. The reaction products have a very low viscosity, which is suitable for processing when about 20% of solvent, based on the non-volatile resin, are added.

标题:Process for the synthesis of phenols from arenes
发明人：MALECZKA JR ROBERT E; SMITH III MILTON R; HOLMES DANIEL; SHI FENG
权利人:UNIV MICHIGAN STATE
摘要:A process to synthesize substituted phenols such as those of the general formula RR'R''Ar(OH) wherein R, R', and R'' are each independently hydrogen or any group which does not interfere in the process for synthesizing the substituted phenol including, but not limited to, halo, alkyl, alkoxy, carboxylic ester, amine, amide; and Ar is any variety of aryl or hetroaryl by means of oxidation of substituted arylboronic esters is described. In particular, a metal-catalyzed C-H activation/borylation reaction is described, which when followed by direct oxidation in a single or separate reaction vessel affords phenols without the need for any intermediate manipulations. More particularly, a process wherein Ir-catalyzed borylation of arenes using pinacolborane (HBPin) followed by oxidation of the intermediate arylboronic ester by OXONE is described.
