Modified polypropylene and polymer blends thereof

A propylene-based polymer composition is characterized by a melt strength at 190° C. of at least 20 cN, a melt drawability at 190° C. of at least 100 mm/s, and a flexural modulus at room temperature of at least 240,000 psi. The propylene-based polymer composition includes a propylene-based polymer resin... Braskem America Inc

Long-chain branched polymers and production processes

This invention relates to a process for forming a long-chain branched polymer and a long-chain branched polymer resulting from the process. The process comprises reacting (a) a polyolefin base polymer with (b) a coupling agent comprising a polymeric coupling agent, optionally blended with a molecular coupling agent, the polymeric coupling... Braskem America Inc

Composition comprising polypropylene and polyol, and making the same

A composition includes (a) a polypropylene or a polypropylene copolymer, (b) a polycarbonate polyol, and (c) optionally an organic peroxide. The polyol (b) is in the range of from about 0.01 wt. % to about 25 wt. % of the total weight of (a), (b) and (c). The method of... Braskem America Inc

Clear and impact resistant polymer composition and fabricated article

A polymer composition providing optical clarity and impact resistance includes from about 40 weight percent (wt. %) to about 99.9 wt. % (e.g., 50-95 wt. %) of a continuous matrix, and from about 0.01 wt. % to about 60 wt. % (e.g., 5-50 wt. %) of a dispersed phase. The... Braskem America Inc
