Abstract: A method for preparing rigid polyurethane (PUR) foams or rigid polyisocyanurate (PIR) foams in which method the rigid PUR or PIR foam is prepared by reacting a composition (C) comprising: at least one isocyanate-reactive component (B1) having functional groups selected from hydroxyl, amine and thiol groups; at least one isocyanate component (A1) having an average functionality of less than 2.70; and at least one blowing agent [blowing agent (BA), herein after]; with the proviso that the overall average functionality [Fn,avg(A), herein after] of all isocyanate components present in the composition (C) is less than 2.

Abstract: The present invention relates to a compound of formula (I) or a stereoisomer, enantiomer, racemic, or tautomer thereof, formula (I) wherein r, R1, R2, R3, R4, R5, R6 and L1 have the meaning defined in the claims and the description. The present invention also relates to a process for the preparation of the compound of formula (I). The present invention also relates to a composition comprising the compound of formula (I). The present invention also relates to a polyurethane or polyurethane prepolymer obtainable by contacting at least one isocyanate with at least one compound of formula (I), or with a composition comprising a compound of formula (I). The present invention relates to the use of such polyurethane or polyurethane prepolymer, or a compound of formula (I), or a composition comprising a compound of formula (I), for the preparation of foams, adhesives, coatings, or elastomers.

Abstract: The present invention concerns heterophasic propylene copolymers, comprising a propylene homopolymer (PPH) and an ethylene-propylene rubber (EPR), having a very broad molecular weight distribution, a well-defined total ethylene content and a specific intrinsic viscosities of the ethylene-propylene rubber (EPR). The invention further concerns the process to produce such heterophasic propylene copolymers. The heterophasic propylene copolymers of the present invention are particularly suited for pails, pallets, IBCs and crates. In particular, the heterophasic propylene copolymers of the present invention are characterized by an improved resistance to creep.

Abstract: The thermoset, phase-separated polyurethane material of the flexible skin layer is produced from a reactive mixture which is made of one or more isocyanate compounds and isocyanate reactive compounds which include one or more polyol compounds, flexibilizers, chain extenders and/or crosslinkers and amine-initiators. Apart from at least one crosslinking amine-initiator, these amine-initiators further include at least one extender amine-initiator.

Abstract: A resin composition comprising at least 0.1% by weight of poly(hydroxy carboxylic acid) and at least 50% by weight of polypropylene prepared with a single-site catalyst, preferably with a metallocene catalyst.
