摘要： The present invention is directed to a foamable polyolefin composition which is crosslinkable by silane groups, to a crosslinked foam obtained from such a foamable polyolefin composition, and to a process for producing a crosslinked foam based on the foamable polyolefin composition. The foamable polyolefin composition comprises a polyethylene bearing hydrolysable silane groups and comonomer units comprising a polar group selected from the group consisting of acrylic acid, methacrylic acid, acrylates, methacrylates, vinyl esters, and mixtures thereof, a silanol condensation catalyst, a physical blowing agent, and a cell nucleating agent.

摘要： The present invention relates to a polymer blend and the film of the polymer blend or the film layers of the polymer blend as a surface layer or coating. More particularly, the invention relates to a polymer blend which may be extruded as such or extruded onto one or both sides of packaging film to give a sealing surface(s) which exhibits surprisingly heat sealability suitable for form-fill-and-seal-packaging. The present invention also relates the use of ethylene based plastomer to reduce sealability of films comprising polypropylene.

摘要： The patent application discloses a polypropylene-plastomer-blend comprising ethylene-based plastomer, which—after conversion into final articles and exposing to surface modification like corona treatment, shows improved dyne retention behavior and improved dyne retention ratio over time. Further disclosed are final articles and a process how to provide compositions and final articles having improved dyne retention behavior.
