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.

An oil-resistant agent including a graft polymer obtained by graft modification of a bio-based material with a long-chain hydrocarbon group-containing non-fluorine polymer having a long-chain hydrocarbon group having 7 to 40 carbon atoms. Also disclosed is a fiber product including the graft polymer in the oil-resistant agent and a method for producing the oil-resistant agent.

A preparation method of a hydrogel of a mercapto-modified macromolecular compound includes the steps of combining the mercapto-modified macromolecular compound with an acrylated macromolecular compound and/or an acrylated micromolecular crosslinker. The mercapto-modified macromolecular compound can be crosslinked with the acrylated macromolecular compound and/or the acrylated micromolecular crosslinker under physiological conditions to form the hydrogel. Due to the rapid mercapto-vinyl crosslinking reaction, the formed hydrogel system can be quickly gelled in situ after being injected into the body. The hydrogel is thus suitable for use in the fields of biomedicine, medical cosmetic plastic surgery and cosmetics.
