    Abstract: PROBLEM TO BE SOLVED: To provide a reprocessable thermoplastic elastomer composition comprising a thermoplastic polyurethane polymer (A) and a silicone elastomer (B) in which the weight ratio of the silicone elastomer to the thermoplastic polyurethane polymer is 5:95 to 85:15, and to provide a method for producing the same.
    SOLUTION: The thermoplastic elastomer composition comprises the thermoplastic polyurethane polymer (A) and the silicone elastomr (B). The silicone elastomer (B) has a Williams plasticity of at least 30 and is a reaction product of dynamic vulcanization, containing 100 pts.wt. of diorganopolysiloxane rubber (B') having the average of at least two alkenyl groups in a molecule, at most 200 pts.wt. of reinforcing filler (B'') for some cases, an organic hydride silicon compound (C) having the average of at least two hydrogen atoms bonded to silicon in a molecule, and a hydrosilylating catalyst (D) where the amounts of the component (C) and (D) contained are sufficient to harden the diorganopolysiloxane (B'). The weight ratio of the silicone elastomer and the thermoplastic polyurethane polymer is 5:95 to 85:15. The thermoplastic elastomer composition is reprocessable.

    Abstract: Water-continuous emulsion of elastomeric polymers are disclosed having a solids content of greater than 75%, an average particle size less than 5 mum, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water comprising; an elastomeric polymer, surfactant, water, optional plasticizer, optional low molecular weight acid, and is essentially free of organic solvents. The water-continuous emulsions of elastomeric polymers can be prepared by; (I) forming a premix that is essentially free of organic solvents comprising an elastomeric polymer and surfactant, and optionally a plasticizer and low molecular weight acid, and (II) adding water to the premix with mixing to form a water continuous emulsion of the elastomeric polymer having a solids content of greater than 75%, an average particle size less than 5 mum, and having sufficient stability to produce a stable lower solids emulsion upon dilution with water.
