THERMOPLASTIC ELASTOMER COMPOSITION HAVING LOW DENSITY AND GOOD MECHANICAL PROPERTIES BY USING UNCOATED HOLLOW GLASS SPHERES
A thermoplastic elastomer composition contains a styrene block copolymer (SBC), a polyolefin or copolyester-based thermoplastic elastomer and uncoated hollow glass spheres, wherein the polyolefin or thermoplastic elastomer is functionalized by a grafting reaction with a vinyl alkoxysilane, a vinyl acyloxysilane, a methacryloxyalkyl alkoxysilane or a methacryloxyalkyl acyloxysilane or with an anhydride of an unsaturated organic acid. A method for producing a thermoplastic elastomer using the thermoplastic elastomer composition, and the thermoplastic elastomer obtained in the process are also disclosed. Furthermore, various uses of the thermoplastic elastomer, in which a thermoplastic elastomer having low density and yet good mechanical properties is required, are disclosed.
