Latest Patents
Leeder's latest patents include a ternary thermoplastic molding composition containing ethylene-propylene. This composition is formed from an admixture of a modified ethylene-propylene copolymer, a propylene polymer, and polyethylene. The formulation contains 35-50% by weight of the modified ethylene-propylene copolymer, which is prepared through the polymerization of an ethylene-propylene copolymer onto polyethylene. The ethylene content of the copolymer is at least 65% by weight, and the modified copolymer has a melt index MFI (230/5) of 0.8-2.0 g/10 min. Additionally, he has developed another ternary thermoplastic molding composition containing polypropylene. This composition consists of 38-48% by weight of a partially crystalline ethylene-propylene copolymer, 27-63% by weight of a polypropylene homopolymer, and 3-30% by weight of polyethylene. The resulting molding composition exhibits a melt index MFI (230/5) of at least 8 g/10 min, a tensile strength of at least 15 N/mm², and an elongation at yield of at least 450%.
