The present invention relates to a method for the manufacture of polypropylene having a target melt flow rate of from 10 to 200 g/10 min as determined in accordance with ISO 1133 (230 C., 2.16 kg) comprising the sequential steps of i) polymerizing propylene monomer, and optionally one or more alpha olefin co-monomers so as to form a polypropylene having an initial melt flow rate of from 0.5 to 20 g/10 min (ISO 1133, 230 C., 2.16 kg), ii) visbreaking said polypropylene to obtain polypropylene having said target melt flow rate and wherein the ratio of target to initial melt flow rate is more than 1 iii) maintaining the polypropylene obtained from step ii) at an elevated temperature for a time sufficient to reduce the FOG value of the polypropylene as determined in accordance with VDA 278. The method allows the time for FOG reduction to be reduced as compared to polypropylenes that have the same target melt flow rate, yet which have obtained said melt flow rate without the visbreaking step.

The invention relates to an adhesive composition wherein such composition comprises at least one polypropylene copolymer and wherein such adhesive composition has improved overall bond performance. It further relates to an article comprising said adhesive composition, as well as to a process for producing such article. It even further relates to the use of the adhesive composition in the preparation of an article.

The invention provides adhesives comprising at least one polymer component which contains at least 65 weight percent propylene, at least one nucleator and at least one functionalized wax. The inventive adhesives have increased heat resistance and decreased set-time, making them particularly well suited for assembly and packaging applications.

A composition and method for producing high-density polyethylene (HDPE) pails with elevated post-consumer recycled (PCR) content. HDPE recyclate is modified to form a modified HDPE recyclate. A blend comprising a majority of the modified HDPE recyclate and a linear low-density polyethylene (LLDPE) is provided as a substitute for virgin HDPE currently used in production of injection molded pails. By employing thermal visbreaking technology alongside specialized recipe formulation, the resulting composition matches or surpasses the processability and key performance attributes of conventional virgin HDPE pails.

A process is provided for preparing a long chain branched polypropylene composition. The process comprises the steps of: i) providing a long chain branched polypropylene. ii) providing a poly functionally unsaturated compound, iii) optionally providing a radical initiator, iv) combining the long chain branched polypropylene, the polyfunctionally unsaturated compound, and the optional radical initiator, to provide a mixture, v) melt extruding the mixture to obtain a long chain branched polypropylene composition. A long chain branched polypropylene composition is provided which is obtainable by melt extruding a mixture comprising: (a) a long chain branched polypropylene, (b) a polyfunctionally unsaturated compound, and (c) optionally a radical initiator. Also provided is a use of a poly functionally unsaturated compound for reducing the loss of melt strength of a long-chain branched polypropylene, and preferably a reused long chain branched polypropylene, during melt extrusion.
