摘要:
A thermoplastic elastomer prepared by a process comprising reacting an elastomer containing at least one reactive halogen atom with a poly(R1(R2)ethylene-co-maleimide) in the presence of a compatibilizer that reduces surface tension between the elastomer and the poly(R1(R2) ethylene-co-maleimide) and in the presence of a Lewis base catalyst, where R1 is a monovalent organic group and R2 is hydrogen or a monovalent organic group.

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.

The present invention teaches a method for enabling the formation of a high damping, soft polymer gel. The method includes: reacting a poly(.alpha.-olefin-co-maleimide) polymer with a maleated polyalkylene and an alkyl diamine under substantially dry conditions sufficient to form a polyalkylene grafted poly(.alpha.-olefin-co-maleimide) polymer product; and, dispersing the polyalkylene grafted poly(.alpha.-olefin-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.
摘要:
A composition includes a diene rubber and a metal phosphate ester of the formula: M being a metal with an oxidation state of +3 or +4, and R1 and R2 are independently selected from any organic moiety including hydrogen, except R1 and R2 cannot both be hydrogen. In addition, a method of making a rubber composition includes combining a solvent and a phosphate ester and mixing these to form a solution. A source of metal ions is then added to the solution. The metal in the source of metal ions is selected from the group consisting of metals with an oxidation state of +3 or +4. The product is then is combined with a diene rubber composition to form a useful article, such as the tread of a tire.

A composition includes a polymer matrix, a multiple-acid-derived metal soap, wherein the metal has an oxidation state of +3 or +4. An associated method for making a rubber composition includes the steps of: combining a solvent and a multiple carboxylic, phosphonic, phosphoric, sulfuric, or sulfonic acid, or mixtures thereof, and mixing to form solution A; adding a source of metal ions to solution A and mixing to form a product A, the metal being selected from the metals having an oxidation state of +3 or +4, whereby product A includes a multiple-acid-derived metal soap; and combining the multiple-acid-derived metal soap with a diene rubber. A method of making a tire component includes the steps of: combining a solvent and a multiple carboxylic, phosphonic, phosphoric, sulfuric, or sulfonic acid, or mixtures thereof, and mixing to form solution A; adding a source of metal ions to solution A and mixing to form a product A, the metal being selected from the metals having an oxidation state of +3 or +4, whereby product A includes a multiple-acid-derived metal soap; combining the multiple-acid-derived metal soap with a diene rubber; and molding and vulcanizing the rubber composition into a tire component.
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.
