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:Methods for the synthesis of fatty diacids by the metathesis of unsaturated diacids obtained by fermentation of natural fatty acids
发明人：DUBOIS JEAN-LUC
权利人:DUBOIS JEAN-LUC; ARKEMA FRANCE
摘要:The invention relates to a method for the synthesis of diacids of general formula ROOC—(CH 2 ) n —(CHâ•?CH) a —(CH 2 ) m COOR 1 in which n and m are identical or different and each represent an integer such that their sum is between 6 and 15, a is an index of 0 or 1, and R and R 1 are H or an alkyl radical with 1 to 4 carbon atoms, from long-chain mono-unsaturated natural fatty acids or esters having at least 10 adjacent carbon atoms per molecule of the general formula CH 3 —(CH 2 ) p —CHâ•?CH—(CH 2 ) q —COOR, p and q, being identical or different and representing indices between 2 and 11, wherein said method comprises the first step of oxidizing by fermentation said natural fatty acid or ester, using a microorganism, such as a bacterium, a yeast, or a fungus, into at least one unsaturated dicarboxylic acid or dicarboxylate, the second step of submitting the product from the first step to a metathesis crossed with a compound of formula R 2 OOC—(CH 2 ) x —CHâ•?CH—R 3 , in which R 2 is H or an alkyl radical with 1 to 4 carbon atoms, x is 0 or 1 or 2, and R 3 is H, CH 3 or COOR 2 , in order to obtain the unsaturated compound of formula ROOC—(CH 2 ) q —CHâ•?CH—(CH 2 ) x —COOR 2 , and the third optional step of converting the usaturated compound into a saturated compound by hydrogenation of the double bond.
