Abstract:
This invention is a method of preventing phase separation of hydrous ethanol and liquid hydrocarbon fuel mixtures comprising the addition of an effective amount of a phase separation inhibitor selected from the group of alkyl acetates which have:(a) a solubility parameter of about 8.4 to 9.8 (cal/cc).sup.1/2 ; and(b) a dipole moment of about 1.75 to 1.90 debye.
Abstract:
.epsilon.-Caprolactam is melt polymerized in the presence of water and from about 0.01 mole percent to less than about 0.6 mole percent of an amine boiling at a temperature greater than 245.degree. C. An amine may be a primary or secondary amine wherein the NH has attached thereto, for example alkyl radicals, cycloalkyl radicals, and the like. The resultant polymer has a methanol extractable content of 3 weight percent or less.
Abstract:
A golf club, particularly a putter, has a unitary body including forward and rearward generally triangular and approximately planar panels merging at their apices with an upright socket adapted to receive a club shank. At their intermediate portions the forward and rearward panels are spaced apart, and at their bases the panels merge with the forward and rearward transverse margins of a ground panel substantially square in plan in a plane normal to the socket axis. The upper face of the ground panel has an upstanding, massive hump. One, or preferably both, of the side margins of the ground panel forms a substantially upright impact face.
Abstract:
Crystalline polymers are readily dissolved in chlorinated diphenyl ether solvents. These solvents and in particular the isomers of chlorodiphenyl ether are especially suitable as solvents for polyarylene sulfides. These solvents are biodegradable and can be conveniently used as alternatives to polychlorobiphenyl solvents.
Abstract:
Mixtures of curable neutral and acid-catalyzed phenol-aldehyde resins and portland cement have been found to provide fast-curing, durable adhesive bonds for wood, masonry, and the like which for many applications are of improved strength as compared to those obtained with known bonding agents. Of particular interest are the compositions where the resin is an arylamine-modified phenol-formaldehyde resin.
Abstract:
N,N'-diglycidyl-N,N'-dialkyl aryl disulfonamides are prepared having an epoxy equivalent weight range from about 234 to about 1100. These polyepoxides are useful to make coated articles having superior solvent resistance and impact resistance when cured with conventional epoxy curing agents.
