Abstract

Termoplastisk blanding med elastisk hukommelse omfatter en blanding av 5 til 20 vekt-deler eventuelt fornettet polynorbornen, 80 til 95 vekt-deler av minst et polyolefin og en mengde mykner for polynorbor- nenet tilstrekkelig til å redusere glassdannelses- temperaturen til gummlområdet. Fortrinnsvis velges som polyolefin en blanding omfattende 80 til 100 % av minst en kopolymer av etylen og minst et a-olefin valgt blant propylen og buten-1 Idet kopolymeren har en densitet mellom 0,850 og 0,890, en fluiditetslndeks mellom 0,3 og 15 dg/min, og O til 20 % av minst en polypropylenpolymer. Gjenstander fremstilt fra den termoplastiske blanding finner hovedsakllg anvendelse som pakninger, sko- elementer, myke slanger, vibrasjonsdempere, profiler for bygnings- og bilindustrien og lignende.Thermoplastic blend with elastic memory comprises a blend of 5 to 20 parts by weight of optionally crosslinked polynorbornene, 80 to 95 parts by weight of at least one polyolefin and a plurality of softeners for the polynorborne sufficient to reduce glass formation temperature to the rubber region. Preferably, as a polyolefin, a mixture comprising 80 to 100% of at least one copolymer of ethylene and at least one α-olefin selected from propylene and butene-1 is selected. The copolymer has a density between 0.850 and 0.890, a fluidity index between 0.3 and 15 dg / day. min, and 0 to 20% of at least one polypropylene polymer. Objects made from the thermoplastic mixture are mainly used as gaskets, shoe elements, soft hoses, vibration dampers, profiles for the building and automotive industry and the like.
