Disclosed are footwear soles comprising a propylene-based elastomer. The presence of the propylene-based elastomer provides the footwear sole with a well-balanced combination of desired properties, including low density, low compression set, and weldability.

Footwear sole comprising a propylene-based elastomer, footwear comprising said sole, and methods of making them

Described herein are thermoplastic vulcanizates comprising propylene-based elastomers and methods for producing the same. The thermoplastic vulcanizates comprise rubber, at least 10 wt % of thermoplastic resin, from 1 to 9 wt % of propylene-based elastomer, oil, and at least 5 wt % of one or more fillers. The thermoplastic vulcanizates are made by a method where the propylene-based elastomer is introduced to the extrusion reactor before the curative is introduced to the extrusion reactor.

Thermoplastic vulcanizates comprising propylene-based elastomers and methods for making the same

Provided are compositions comprising: (i) a dispersed phase of rubber that is at least partially cured; (ii) a continuous thermoplastic phase including at least one thermoplastic polymer; (iii) a first polysiloxane having a number average molecular weight greater than 100 kg/mole; and (iv) a second polysiloxane having a number average molecular weight less than 100 kg/mole, and methods for making such compositions. Also provided are laminates including such compositions, weatherseals made therefrom, and methods for making them.

Compositions and methods for making them

An underwater pelletizing method for pelletizing brittle hydrocarbon resins with low melt viscosity. A feed material comprising the hydrocarbon resin is formed into a melt, extruded through a die into a water bath below the Tg of the hydrocarbon resin to form a plurality of extrudates and cut adjacent the die surface to form a slurry of resin pellets. A graft monomer and/or other reactants, such as a hydrosilylation agent, may be introduced into the resin melt to chemically modify the hydrocarbon resin.

Underwater pelletizing method for low viscosity hydrocarbon resins

Provided are methods for producing a thermoplastic vulcanizate. One method includes charging vulcanizable rubber to a reactor; charging a masterbatch of thermoplastic resin and a catalyst for a phenolic resin curative to the reactor; charging a phenolic resin curative to the reactor; and dynamically vulcanizing the rubber with the phenolic resin curative in the presence of the catalyst. Also provided are thermoplastic vulcanizates made by the methods of the invention.

Process for forming thermoplastic vulcanizates

A weatherable, flame-resistant thermoplastic vulcanizate composition comprising a thermoplastic matrix; and dispersed within said matrix, an at least partially cured rubber, a flame retardant, and carbon black.

Weatherable and flame-resistant thermoplastic vulcanizates and methods for making them

A flame-retardant composition having (a) a copolymer comprising at least about 50 wt. % of propylene-derived units, and about 5-35 wt. % of units derived from at least one of ethylene or a Calpha-olefin, wherein the copolymer has a heat of fusion of about 75 J/g or less; and (b) a flame retardant, wherein the composition satisfies the requirements of UL94 with a V2 rating.

Flame resistant polyolefin compositions and methods for making the same

A closed cell foam material contains a propylene based polymer comprising from about 5% to about 32% by weight &#x3b1;-olefin units. The propylene based polymer has a heat of fusion, as determined by DSC, of less than 80 J/g. The material also contains 0.5 to 5 phr peroxide, 1.0 to 5.0 phr blowing agent, and 0.1 to 10 phr co-agent. The cells of closed cell foam material have a diameter in the range of 0.1 to 1.5 mm.

Closed cell propylene-ethylene foam

Provided are thermoplastic elastomer compositions, many dynamically vulcanized, with superior crystallization kinetics, methods for making the compositions and articles made therefrom. The thermoplastic elastomer compositions comprise at least a propylene polymer thermoplastic, a rubber and a crystallization additive. The processes for preparation of the thermoplastic elastomer compositions comprises dynamic vulcanization of mixture of a propylene polymer thermoplastic, a rubber and a cure agent followed by addition of a crystallization additive. Further, preparation of articles from the thermoplastic elastomer compositions may be accomplished through traditional thermoforming operations useful with conventional thermoplastics.
