FIELD: chemistry. ^ SUBSTANCE: mixture contains two different polyolefin and ethylene/-olefin copolymers. The ethylene/-olefin copolymer is a block-copolymer containing at least one hard block and at least one soft block. The ethylene/-olefin copolymer can function as a component which improves compatibility between two polyolefins which may be incompatible. The disclosed polymeric mixtures can be used in making various articles such as tyres, hoses, belts, linings, shoe soles, cast and moulded articles. Said mixtures are especially useful for applications requiring melt strength, such as big articles made by blow moulding, foam and bundled bars. ^ EFFECT: improved compatibility of mixtures. ^ 27 cl, 10 dwg, 13 tbl, 40 ex |
