A method of making a graft copolymer, comprising the steps of obtaining a first polymer comprising at least one carbon-carbon double bond, the first polymer derived from at least one first monomer, the at least one first monomer comprising a conjugated diene monomer; obtaining a second polymer, the second polymer capable of exhibiting a lower critical solution temperature (LCST) and comprising a terminal functional group capable of reacting with the carbon-carbon double bond; and reacting the second polymer with the first polymer to form a graft copolymer, the graft copolymer comprising a backbone derived from the first polymer and sidechains derived from the second polymer.

Method of making a graft copolymer

The present invention is directed to a polymer blend, the blend including a diene-based elastomer grafted with a substituted acrylamide polymer through a sulfur atom, and from 1 to 20 percent by weight of an additional polymer miscible with the substituted acrylamide polymer.

Blend of a graft copolymer and a second polymer miscible with sidechains of the graft copolymer

The present invention is directed to a copolymer comprising: a polymeric backbone chain derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer; and polymeric sidechains bonded to the backbone chain, the sidechains comprising a polymer capable of exhibiting a lower critical solution temperature (LCST).

Graft copolymer

The present invention is directed to a functionalized elastomer comprising: a polymeric backbone chain derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer; and a functional group bonded to the backbone chain, the functional group comprising a multidentate ligand capable of complexing with a metal ion.

Functiontionalized elastomer

The present invention is directed to a method of making a graft copolymer, comprising the steps of:

The present invention is directed to a vulcanizable rubber composition comprising: a diene based elastomer; and a compound of formula I where Q is an n-valent organic group of 1 or more carbon atoms and optionally one or more of nitrogen, oxygen, sulfur, halogen, silicon, and phosphorus atoms;X is a divalent polymer group capable of exhibiting a lower critical solution temperature;R is independently a hydrogen atom or a monovalent group of formula (II) where Z is a monovalent organic group of 1 or more carbon atoms and optionally one or more of nitrogen, oxygen, sulfur, halogen, silicon, and phosphorus atoms; andn is an integer greater than or equal to 2. The invention is further directed to a rubber composition comprising the reaction product of a diene based elastomer and a compound of formula I, and a pneumatic tire with a tread comprising the rubber composition.

Rubber composition and pneumatic tire

The invention relates to an ink jet ink composition containing monodisperse polymer particles to provide an opaque ink with improved color brilliancy, ink jet ink sets based on this composition, and a methods for ink jet printing with the ink and/or ink jet sets.

Ink jet ink composition

A multi-layer coating for coating a substrate surface, comprising at least one color-imparting layer, which contains three-dimensional photonic crystals as effect-imparting interference pigments.
