Latest Patents

Luiza holds a patent for "Heterophasic propylene copolymers, methods, films, and articles thereof." This patent describes heterophasic propylene copolymer compositions that include a polymer matrix of a random propylene copolymer and an elastomeric copolymer. The elastomeric copolymer is dispersed in the polymer matrix in an amount ranging from about 10 to 35 wt. %, relative to the weight of the composition. The random propylene copolymer may include one or more comonomers in an amount ranging from about 0.5 to 8.0 wt. % of the random propylene copolymer. The elastomeric copolymer may include propylene and one or more comonomers, where the comonomers are present in an amount ranging from about 15 to 60 wt. % of the elastomeric copolymer. Films can be formed from these heterophasic propylene copolymer compositions, and methods of preparing them may include performing a multistage polymerization.
