摘要： 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.

摘要： Various adhesive compositions are described which may optionally comprise one or more active agents such as pharmaceutical agents. The incorporation of one or more absorbents in combination with one or more crystallization inhibitors improves adhesive characteristics of the compositions. Also described are related methods of improving adhesive characteristics of adhesive compositions with the use of a combination of absorbent and inhibitor. Also described are related methods of using the compositions and articles incorporating such compositions.

摘要： A composition is described comprising a styrene-isobutylene block copolymer; and at least one ethylenically unsaturated monomer. After curing the composition comprises polymerized units of the ethylenically unsaturated monomer. In some embodiments the ethylenically unsaturated groups are selected from (meth)acryl or vinyl ether. The composition is suitable for use as a (e.g. pressure sensitive) adhesive. Articles, methods of making an article, and methods of bonding are also described.
