The present invention teaches a method for enabling the formation of a high damping compound. The method includes: reacting a poly(disubstituted ethylene-co-maleic acid anhydride) polymer with a primary amine under substantially dry conditions sufficient to form a poly(disubstituted ethylene-co-maleimide) polymer plasticizer; and, dispersing the poly(disubstituted ethylene-co-maleimide) polymer plasticizer within a rubber formulation to form a relatively high damping compound.
摘要:
Rubber curing agents such as quinoids are compounded to achieve a uniform or homogeneous distribution thereof in a rubber composition. The quinoid curing agents are initially solubilized in an organic polar solvent and then mixed with the rubber or rubber masterbatch. The organic polar solvent is then removed. A uniform fine distribution of the curing agent results in improved physical properties. The process is an improvement in that it does not require the rubber masterbatch be dissolved in a nonpolar solvent. The present invention is particularly suitable as a sealant composition for tires.

The present invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting a poly(alkyl vinylether-co-maleimide) polymer with a maleated polyalkylene and an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(alkyl vinylether-co-maleimide) polymer product; and, dispersing the polyalkylene grafted poly(alkyl vinylether-co-maleimide) polymer product with an extender oil sufficient to form the gel. The present invention also contemplates a polymer gel composition, a polymer composition and an article manufactured from the polymer gel composition.

The present invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting in a suitable solvent a poly(alkenyl benzene-co-maleic anhydride) and a primary amine to form a poly(alkenyl benzene-co-maleimide) polymer. The poly(alkenyl benzene-co-maleimide) polymer while remaining in solvent is grafted with a maleated polyalkylene through the use of a grafting agent such as an alkyl diamine to form a polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product. The solvent is then removed from the polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product and the polymer is mixed with extender such as oil sufficient to form the gel. During oil extension the graft copolymer is further crosslinked due to the presence of additional alkyl diamine.

The instant invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting a poly(maleimide-co-alkenyl benzene) polymer with a nylon and an alkyl diamine under substantially dry conditions sufficient to form a nylon grafted poly(maleimide-co-alkenyl benzene) polymer product; and, dispersing the nylon grafted poly(maleimide-co-alkenyl benzene) polymer product with an extender oil sufficient to form the gel. The instant invention also contemplates a polymer gel composition, a polymer composition and an article manufactured from the polymer gel composition.
摘要:
Compositions and methods for preparing at least partially hollow nanoparticles having an outer shell comprising a one or more molecules and/or residues derived from a metal soap, where the nanoparticles each comprise a continuous inner void space that averages at least 10 percent of the volume of each of the nanoparticles. Such at least partially hollow nanoparticles can be employed in a variety of applications including, but not limited to, tire manufacturing.
摘要:
This invention relates to rubber compositions having a low aromatic-oil content, or no aromatic oils at all. The rubber composition contains a diene rubber, one or more fillers, and a low molecular weight, functionalized polymer than has the ability to interact with the fillers and act and as a replacement to the aromatic oil. The rubber compositions so produced may be used in tread rubbers and have exhibited good snow/wet traction properties and low rolling resistance.
摘要:
The present invention provides a rubber composition comprising (a) a liquid polymer, (b) polymer nanoparticles, and (c) a rubbery matrix. The composition may comprise less or even no aromatic oil. Rubber articles manufactured from such composition, such as tires and power belts, have gained improved reinforcement and controllable hysteresis properties.
