摘要： A composition comprising (A) from 10 wt% to 90 wt% of a propylene component including at least one propylene based polymer having a propylene content of at least 50.0 wt%, based on the total weight of the propylene based polymer, and a melt flow rate from 0.5 g/10 min to 200.0 g/10 min (ASTM D-1238 at 230°C, 2.16 kg); (B) from 1 wt% to 60 wt% of a polyolefin elastomer; (C) from 1 wt% to 20 wt% of a block composite comprising (i) an ethylene-propylene copolymer, (ii) an isotactic polypropylene copolymer, and (iii) a block copolymer including an ethylene-propylene soft block that has a same composition as the ethylene-propylene copolymer of the block composite and an isotactic polypropylene hard block that has a same composition as the isotactic polypropylene copolymer of the block composite; and (D) optionally, from 0.1 wt% to 10 wt% of an antioxidant.

摘要： A polyolefin-based composition showing improved weldability using high frequency (HF) includes (1) a base polymer selected from (a) a homogeneously branched, linear or substantially linear ethylene/α-olefin copolymer; (b) a homogeneously branched propylene/α-olefin copolymer; or (c) a combination thereof; and (2) at least one secondary component selected from (a) an ethylene vinyl acetate copolymer having from 5 to 40 wt % vinyl acetate; (b) an ethylene-ethyl acrylate having from 5 to 25 wt % ethyl acrylate; and (c) a combination thereof. The combination of the specified polyolefin with the specified secondary component, which is a polar polymer, makes these formulations HF weldable, with a cohesive welding failure, a weld strength for 10 mil thick film greater than 7 lb/in (1.23 N/mm) at a weld time of less than or equal to 6 seconds. The formulations may also exhibit good calendering processability and mechanical properties.
