New additives in rubber compositions improve tire cord adhesion without need to use resorcinol. The new additives are derivatives of melamine, aceto guanamine, benzoguanamine, cyclohexylguanamine, and glycoluril, substituted with at least two vinyl-terminated radicals. Preferred compounds may also be substituted with at least one radical having a carbamylmethyl group.

Additives for improving tire cord adhesion and toughness of vulcanized

An improved process for the synthesis of esters of 3,5,6-trichlorosalicylic acid in quantitative yield comprises reacting the acid with an alcohol under distillation conditions in the presence of a titanium ester or chelate catalyst, whereby byproduct ether formation from the alcohol is suppressed. The process is especially applicable to a process by which salicylic acid is chlorinated first in concentrated sulfuric acid and then with iodine catalyst to make the trichlorosalicylic acid which is extracted and then reacted with an alcohol and a titanium catalyst to make the ester.

Process for preparing esters of 3,5,6-trichlorosalicyclic acid

A method of making a copolymer of meta- or para-isopropenyl- .alpha.,.alpha.-dimethylbenzylisocyanate and at least one other ethylenically unsaturated comonomer polymerizable therewith, comprising polymerizing the meta- or para-isopropenyl- .alpha.,.alpha.-dimethylbenzylisocyanate and at least one other ethylenically unsaturated comonomer in an aqueous emulsion in the presence of a free-radical polymerization initiator and a chain transfer agent to control molecular weight. Also disclosed are methods of breaking the aqueous emulsion after polymerization is completed by either adding a salt, e.g., aluminum sulfate, or by freezing the emulsion followed by thawing to yield the copolymer as a mechanically separable solid phase of a two-phase liquid-solid mixture.

Cellulose dissolved in a suitable solvent and added to an aqueous suspension of paper-making cellulose fibers provides paper of improved dry strength.

Use of a dissolved cellulose as a dry strength agent and drainage aid

Water-dispersible but water-insoluble vinyl polymers composed of at least 40 mol percent of hydrophilic cationic linkages, at least 5 mol percent of hydrophobic linkages and up to 10 mol percent of hydrophilic anionic linkages are flocculating agents for the solids in industrial effluents (including raw and digested sewage). The polymers form stable dispersions in water, and are employed in that state.
