Use Of Rubber Solvent-Resin Solvent And Miscella Mixtures For Extraction-Expression Of Rubber And Resins From Guayule Shrub

View page
US Patent:
46819290, Jul 21, 1987
Filed:
Apr 29, 1985
Appl. No.:
6/728366
Inventors:
William M. Cole - Norton OH
Steven L. Fenske - Uniontown OH
David J. Serbin - Springfield VA
Shrikant R. Malani - Akron OH
Frank J. Clark - Massillon OH
Joanne L. Beattie - Uniontown OH
Assignee:
The Firestone Tire & Rubber Company - Akron OH
International Classification:
C08C 104
US Classification:
528493
Abstract:
A process for extracting resin and rubber from guayule plants utilizing a portion of recycled miscella and a fresh solvent system. An expression step is applied to the plants to enhance recovery of resin and rubber extract. The solvent system is preferably an organic polar solvent and a hydrocarbon solvent for rubber for simultaneous resin and rubber extraction containing at least 50% by weight of the hydrocarbon solvent. The process can be a one-step method wherein resin and rubber are generally simultaneously extracted.

US Patent:
46160752, Oct 7, 1986
Filed:
Apr 4, 1985
Appl. No.:
6/719843
Inventors:
Shrikant R. Malani - Akron OH
Frank J. Clark - Massillon OH
Assignee:
The Firestone Tire & Rubber Company - Akron OH
International Classification:
C08G 8300
C08C 400
US Classification:
528 1
Abstract:
A process and product thereof for densifying guayule shrubs by compression and forming a densified pellet. The densified pellet substantially maintains its molecular weight during storage over a period of weeks without the aid of any inert gas blanket or the like.

US Patent:
45018669, Feb 26, 1985
Filed:
Jul 23, 1984
Appl. No.:
6/633814
Inventors:
David M. Roggeman - Akron OH
Shrikant R. Malani - Akron OH
Jung W. Kang - Clinton OH
Assignee:
The Firestone Tire & Rubber Company - Akron OH
International Classification:
C08F 482
US Classification:
526133
Abstract:
A method for preparing high cis-1,4 polybutadiene by a continuous process which involves the continuous polymerization of 1,3-butadiene in solution under adiabatic conditions is provided. The method comprises the steps of: (I) feeding continuously to a single agitated polymerization reactor: (a) a monomer stream comprising 1,3-butadiene in a hydrocarbon solvent; (b) a preformed. pi. allyl catalyst stream formed by admixing a carboxylated metal oxy borate compound represented by the formulae (RCOOMO). sub. 3 B or (ROCOOMO). sub. 2 B-OR' wherein R and R' are alkyl radicals containing from 7 to 17 carbon atoms and M is nickel or cobalt, an organo aluminum compound, an alcohol, a small amount of 1,3-butadiene and a hydrocarbon solvent; and (c) a cocatalyst stream comprising a boron trifluoride complex with an alcohol; and (II) withdrawing continuously from said reactor high cis-1,4 polybutadiene at the same rate as said monomer, preformed catalyst and cocatalyst streams are fed to the reactor. In an additional embodiment of the invention, a method of preparing a preformed. pi. allyl catalyst having improved stability and solubility in hydrocarbon solvent is provided.
