It becomes possible to produce a thermoplastic resin composition having a sea-island structure by a kneading step of kneading a thermoplastic elastomer and/or rubber material having an alkoxysilyl group, in which the alkoxysilyl group is grafted to the thermoplastic elastomer and/or rubber material, and a thermoplastic resin in a melt state in a kneading machine and a dynamic crosslinking step of adding a water component into the kneading machine, forming a silanol group by a hydrolysis reaction of the alkoxysilyl group in the thermoplastic elastomer and/or rubber material having an alkoxysilyl group and the water component in the kneading machine, and subsequently forming a siloxane bond by a condensation reaction between the silanol groups.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. In particular, discrete mechanical bonds are applied to a first substrate and a second substrate to secure elastic strands therebetween, wherein the discrete bonds are arranged intermittently along the machine direction. During the bonding process, heat and pressure are applied to the first substrate and the second substrate such that malleable materials of the first and second substrates deform to completely surround an outer perimeter of a discrete length of the stretched elastic strand. After removing the heat and pressure from the first and second substrates, the malleable materials harden to define a bond conforming with a cross sectional shape defined by the outer perimeter of the stretched elastic strand.

The present invention relates to thermoplastic olefin elastomer expanded beads, having an average aspect ratio of 1.10 or less and an average circularity of 0.985 or more.

The present disclosure is directed to articles that include a cured coating that includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating can include a matrix of crosslinked polymers. The cured coating is a product of crosslinking a coating composition comprising uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier to form the matrix of crosslinked polymers), wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers. The matrix of crosslinked polymers can be elastomeric. The present disclosure is also directed to articles including these bladders, methods of forming these bladders, and methods of making articles including these bladders, where the bladders include the cured coating.

The present invention relates to bead foams made of thermoplastic polyurethane and polystyrene produced moldings, to processes for the production of the bead foams and moldings, and also to the use of the moldings for shoe intermediate soles, shoe insoles, shoe combisoles, or cushioning elements for shoes.
