The polymer composition of the present invention may comprise a polyolefin and a metallic acrylate salt having a molecular weight distribution of 8 or more as measured by GPC. The polymer composition was then subjected to a melt flow rate of 0.1 g / 10 min to 10 g / 10 min; A melt flow viscosity of from 2,000 Pa.s to 6,000 Pa.s; Die swell of from 2 to 8; And a die swell characteristic time of 0.3 seconds to 1.2 seconds. The polymer composition may be in the form of a foam. The process of forming the foam may include supplying a polymer composition comprising a metallic acrylate salt and a polyolefin resin, and mixing the polymer composition with a blowing agent. The foam may comprise a polymer composition comprising a polyolefin and a polar polymer but not an ionomer. The foam may have a foam density of less than 0.25 g / cc. |
