A method for preparing a functionalized polymer includes the steps of (i) polymerizing monomer to form a reactive polymer; and (ii) reacting the reactive polymer with a [poly(hydrocarbylene glycol) hydrocarbyl ether] (meth)acrylate.

Functionalized polymers having thermoresponsive behavior

Methods for treating the surface of a cured inner liner are disclosed. By use of these methods a treated, cured inner liner is produced which has a lower surface with increased adherability to other materials (e.g., adhesives). Treated, cured inner liners resulting from such methods as well as tires containing the treated inner liners.

Methods for treating inner liner surface, inner liners resulting therefrom and tires containing such inner liners

Disclosed herein are methods for degrading polyurethane foam from mounted polyurethane foam-containing tires, methods for separating a wheel from a mounted polyurethane foam-containing tire, methods for preparing a degradable foam-containing tire, and degradable foam-containing tires. The methods include applying a solution comprising at least one phosphorous oxoacid or an ester thereof to the polyurethane foam inside of a tire, incorporating a degradant comprising at least one phosphorous oxoacid or an ester thereof into the polyurethane foam, or both, and then heating to degrade the foam. Degradation of the foam allows for separation of the wheel from the rubber carcass of the tire.

Methods relating to polyurethane foam-containing and degradable foam-containing tires, and degradable foam-containing tires

Disclosed herein are kits for use in adding degradable foam to a tire, methods for preparing a degradable foam-containing tire, tires containing degradable foam, and methods for degrading the degradable foam in tires containing degradable foam. The degradable foam comprises a combination of (i) at least one di- or polyisocyanate, (ii) at least one polysiloxane diol, at least one polysiloxane diamine, or a combination thereof, and (iii) optionally at least one polyol.

Degradable foam-containing tires, related methods and kits for adding degradable foam to tires

Disclosed herein are processes for production of a cured polymeric product which processes include using rubber particles to form a rubber layer, applying liquid binder to form a bound layer from the rubber layer, and curing, whereby repetition of steps allows for formation of additional layers and ultimately production of the cured polymeric product.

Processes for producing cured polymeric products by additive manufacturing

A method of manufacturing a tread for agricultural tires, the method comprising providing an agricultural tire casing, providing a cured rubber component having first and second planar surfaces, providing a plurality of cushion gums, wherein the plurality of cushion gums contains a cure system comprising a stable dinitrile oxide compound, providing a plurality of lugs, and forming an agricultural tread composite by mating the lugs to a planar surface of the cured rubber component using the cushion gum.

Metallic complexes having indenyl ligands can be used as an ingredient of a catalyst system. The catalyst system can be used in polymerizations of ethylenically unsaturated hydrocarbon monomers that include both olefins and polyenes. Embodiments of the catalyst system can provide interpolymers that include polyene mer and from 40 to 75 mole percent ethylene mer, with a plurality of the ethylene mer being randomly distributed. The catalyst system also can be used in solution polymerizations conducted in C-Calkanes, yielding interpolymers that include at least 10 mole percent ethylene mer.
