  • Patent number: 11197784
    Abstract: An absorbent disposable article, such as a diaper, panty diaper, panty liner, sanitary napkin or incontinence device is disclosed. The article has a porous polymer-based structure obtainable by a process of: (a) depositing and photopolymerizing, layer-by-layer in accordance with a predetermined 3D model, an emulsion having an external continuous phase surrounding droplets of an internal phase having has one or more photopolymerizable monomers and/or oligomers and a photopolymerization initiator; and (b) removing the internal phase from the continuous polymer phase formed from the one or more photopolymerizable monomers and/or oligomers. The process produces a monolithic porous structure having three types of pores: (i) pores resulting from the location from which the internal phase was removed, (ii) pores interconnecting the pores according to (i), and (iii) pores as predetermined by the 3D model. The invention also relates to a method of making the article.

  • Publication number: 20160312007
    Abstract: The present invention relates to a polyolefin composition comprising (A) a polyolefin, (B) a compound comprising, preferably consisting of, the structural unit according to the following formula (I): wherein R is C or N; R1 is hydrogen, a heteroatom or a hydrocarbyl group which may contain heteroatoms; R2, R3, R4, R5, R6, R7, R8 and R9 independently are hydrogen, or a hydrocarbyl group which may contain heteroatoms; or at least two of said R2, R3, R4, R5, R6, R7, R8 and R9 together with the ring atoms of the ring system of formula (I) they are attached to, form a further aromatic or non-aromatic ring fused to the ring system of formula (I); also to a wire or cable, in particular a medium, high or extra high voltage cable, comprising such a composition, and to the use of such a composition for the production of a wire or cable, in particular a medium, high or extra high voltage cable.
