Polymer blends, methods of making the polymer blends, and articles of manufacture that include the polymer blends are described. A polymer blend can include a high density polyethylene (HDPE) polymer and a random block copolymer. The random block copolymer can include two different saturated alkane blocks between aromatic blocks (e.g., two styrenic blocks).

Polyethylene compositions with improved environmental stress cracking resistance and methods of use

The invention relates to a composition obtained by the adsorption of a liquid peroxide onto granules comprising an antioxidant and an acid scavenger, for example wherein the adsorption of the liquid peroxide onto the granules is performed by a process which can be performed at room temperature (23&#xb0; C.) and the process does not require heating.

Additive composition

The invention relates to a biaxially oriented polypropylene (BOPP) film comprising a propylene homopolymer or propylene-ethylene copolymer having an ethylene content of at most 1.0 wt % based on the propylene-ethylene copolymer having an Mw/Mn in the range from 5.0 to 12, wherein Mw stands for the weight average molecular weight and Mn stands for the number average weight and wherein Mw and Mn are measured according to ASTM D6474-12, an XS in the range from 1.0 to 6.0 wt %, wherein XS stands for the amount of xylene solubles which are measured according to ASTM D 5492-10, a melt flow rate in the range of 1 to 10 dg/min as measured according to IS01133 (2.16 kg/230&#xb0; C.) and a crystal size distribution as indicated by a height/width ratio of the highest peak of the first cooling curve of at least 0.70 W/g&#xb0; C. as determined by ASTM D3418-08 using a heating and cooling rate of 10&#xb0; C./min.
