Latest Patents

Quental 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 one or more 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. Quental has 1 patent to his name.
