Abstract: A composition including a first polypropylene having at least 90 wt. % propylene by weight of the first polypropylene, an alpha nucleation inhibitor, and a beta nucleation additive is provided. Also provided is a method of preparing a foamable polypropylene composition. The method includes the steps: a) compounding a first polypropylene including at least 90 wt. % propylene by weight of the first polypropylene with an alpha nucleation inhibitor to form a polypropylene blend; b) compounding the polypropylene blend with a blowing agent to form a pre-annealed polypropylene composition; and c) annealing the pre-annealed polypropylene composition at an annealing temperature Ta for an annealing time ta to form the foamable polypropylene composition. The foamable polypropylene composition has a first melting peak T1 and a second melting peak T2 as measured by differential scanning calorimetry at a heating rate of 20° C. per minute.

Abstract: A method of adjusting a processing parameter of a polymer is provided. The method has the steps a) and b). Step a) is combining polymer i) which is polypropylene and/or polyethylene with a process aid ii) to provide a polymer composition. Polymer i) has a peak molecular weight Mp and a polydispersity index PDI of 7 or higher. Step b) is processing the polymer composition at a processing condition. The processing parameter is adjusted at the processing condition for the polymer composition compared to a comparative polymer composition A); and a comparative polymer composition B). Comparative polymer composition A) lacks the process aid ii) but is otherwise identical to the polymer composition. Comparative polymer composition B) includes a comparative polymer having the same composition and Mp as polymer i) and a PDI less than polymer i) instead of the polymer i), but is otherwise identical to the polymer composition.

Abstract: An adhesive composition made from an elastomer and a tackifying resin. The tackifying resin includes a farnesene polymer or copolymer having the following properties: i) less than 10 weight percent of volatile organic compounds; ii) Mn between 300 Da and 1000 Da; iii) Mw between 400 Da and 3000 Da; iv) Mw/Mn between 1.00 and 3.00; v) Tg between −50° C. and 20° C.; and vi) viscosity between 400,000 cP and 1,000,000 cP at 25° C. A method of making the farnesene-based polymer or copolymer includes combining a farnesene monomer and a solvent and optionally adding one or more co-monomers selected from dienes, branched mono-olefins, and vinyl aromatics, to provide a monomer feed, and polymerizing the monomer feed by combining it with a Friedel-Crafts initiator in a vessel. The farnesene-based polymer or copolymer tackifier may be combined with one or more elastomers and one or more other tackifiers to form an adhesive composition.
