摘要:
The present invention provides a nano-composite comprising a clay and a cationic mediator comprised of a hydrophobic unit and a cationic unit. The clay is exfoliated or intercalated by the cationic mediator. The present invention further provides a polymer formulation comprising the nano-composite. The nano-composite is practically useful in formulating compositions such as rubber and tire products with improved and well-balanced properties including gas permeability, cure properties, and/or mechanical properties etc.

The instant invention relates to poly(maleimide-co-alkenyl benzene) centipede polymer and a method for producing the polymer by reacting a poly(alkenyl benzene-co-maleic anhydride) in the presence of a primary amine in a substantially dry state. The invention is further directed to a process for blending the poly(maleimide-co-alkenyl benzene) centipede polymer with elastomeric polymers, in combination with, or in substitution of, conventional extender oils, to produce extended polymers having improved properties such as tensile strength, maximum elongation, tear strength, damping properties, and the like.
摘要:
The present invention teaches a method for enabling the formation of a high damping compound. The method includes: reacting a poly(alkenyl benzene-co-maleimide) polymer with a maleated polyalkylene and an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product; and, dispersing the polyalkylene grafted poly(alkenyl benzene-co-maleimide) polymer product within a rubber formulation to form a relatively high damping compound. The present invention also contemplates a rubber compound composition and an article manufactured from the composition.
摘要:
A multi-layer nano-particle composition including a polymer core and at least two additional layers is provided. The nano-particles have a mean average diameter less than about 100 nm. The nano-particles can be modified via, for example, hydrogenation or functionalization. The nano-particles can be advantageously incorporated into rubbers, elastomers, and thermoplastics.

摘要:
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.
