HYBRID POLYMER-METAL ARTICLES, PROCESS FOR THE PREPARATION OF HYBRID POLYMER-METAL ARTICLES AND PROCESS FOR THE PREPARATION OF HYBRID POLYMER-METAL ARTICLES

摘要

hybrid polymer-metal article comprising: a surface layer a comprising a polyamide or polypropylene polymer, a thermoplastic adhesive layer b comprising: b1) at least 50% by weight of a non-functionalized thermoplastic polyolefin having a melting point of about 80 at 200 ° c and b2) less than 50 weight percent of a functionalized thermoplastic polyolefin comprising from 0.02 to 10 weight percent of a carboxyl functional group, wherein the content of the carboxyl functional group of layer b ranges from 0 , 02 to 1.5 weight percent and a layer of metal c in an a / b / c structure. these polymer-metal hybrid articles can be overmoulded.
