BINDER FOR COEXTRUSION COMPRISING POLYETHYLENE METALLOCENE |
摘要 |
<p>A coextrusion binder comprising a mixture of a metallocene polyethylene and non-metallocene linear low density polyethylene (LLDPE) cografted with an unsaturated carboxylic acid or derivative, styrene-butadiene-styrene (SBS) block copolymer and polyethylene with a melt fluidity index of 0.1-10 g/10 minutes. The binder comprises 10-35 wt.% of the mixture comprising 80-20 wt.% of a metallocene polyethylene with density 0.815-0.915 and 20-80 wt.% of non-metallocene LLDPE grafted with 30-100000 ppm of carboxylic acid or derivative; 40-60 wt.% of SBS with 50-90 mol.% styrene; 20-35 wt.% polyethylene. Independent claims are included for a multilayer structure comprising a layer comprising the binder and a layer of polystyrene homo- or copolymer attached to one or other of its faces and for an object comprising such a structure.</p> |
