Abstract: Ethylene-vinyl acetate copolymer compositions useful as adhesives, vibration-damping compositions or coating compositions which comprises a saponification product or a grafted saponification product of an ethylene-vinyl acetate copolymer and at least one aliphatic or aromatic polycarboxylic acid or anhydrides thereof.

Abstract: Thread locking compositions and analogous sealant materials having limited cured strength, and a preferred method for their compounding and application, are disclosed. These are based primarily on alpha cyanoacrylates, i.e. acrylate esters in monomer or low polymeric form, or of very low molecular weight, which are rapidly polymerizable to form solid and bonding films. The materials, in liquid form, are modified by inclusion of coloring agents and other film strength and reaction rate modifiers, to impart optimum properties of bonding strength, curing rate, moderate resistance in torque to separation of the bonded parts, low residual torque, along with good stability in storage, or good shelf life. Combinations of polymerization promoters and stabilizers are included, along with small quantities of specially selected coloring agents which not only impart effective color to thin films of the composition but serve to limit curing below high cured strength.
