    Abstract: A thermoplastic elastomer composition for crosslinked foam and the manufacturing method thereof are provided. The thermoplastic elastomer composition comprising (A) an ethylene-based copolymer; (B) a first copolymer; (C) a second copolymer, wherein the component (B) and (C) are copolymers comprising a vinyl aromatic monomer and a conjugated diene monomer, the first copolymer having a conjugated diene hydrogenation rate of at least 80% and the second copolymer having a conjugated diene hydrogenation rate of no more than 10%; (D) an organic peroxide; and (E) a foaming agent, wherein a mass ratio (A/(B+C)) of the component (A) to a combination of the component (B) and the component (C) is 95/5 to 5/95; and a mass ratio (B/C) of the component (B) to the component (C) is 9/1 to 1/9. A crosslinked foam made from the composition and the manufacturing method thereof are also provided.

    Abstract: The present invention provides a polymer composition for fibers or non-woven fabrics, comprising a vinyl aromatic based copolymer and 0 to 30 wt % of an olefin based polymer based on the total weight of the polymer composition. The vinyl aromatic copolymer is represented by a formula A1-B-A2, wherein block A1 and block A2 are the same or different vinyl aromatic blocks, block A1 or block A2 having 3,800 to 4,800 of a peak molecular weight, and block B is a hydrogenated conjugated diene block. A vinyl structure content of a conjugated diene monomer content in the vinyl aromatic based copolymer is from 32 wt % to 50 wt %; and a melt flow index (MFI) of the vinyl aromatic based copolymer is 20 g/10 min˜60 g/10 min (230° C., 2.16 kg). The present invention also provides the fibers or the non-woven fabrics made from the polymer composition.

    Abstract: The present invention provides a polymer composition for pressure sensitive adhesives or films thereof. The polymer composition comprises 20-40 parts by weight of a tackifier; and 60-80 parts by weight of a polymer, wherein the polymer and the tackifier are 100 parts by weight. The polymer comprises at least a first vinyl aromatic based copolymer formed by polymerization of vinyl aromatic monomer and conjugated diene monomer, wherein a vinyl aromatic monomer content of the first vinyl aromatic based copolymer is 16 wt %˜28 wt %, a vinyl structure content of a conjugated diene monomer content in the first vinyl aromatic based copolymer is 32 wt %˜50 wt %; and a melt flow index (MFI) of the first vinyl aromatic based copolymer is 20 g/10 min˜60 g/10 min (230° C., 2.16 kg). The present invention also provides the pressure sensitive adhesives or films made from the polymer composition.
