Abstract (en)

[origin: WO9325617A2] Paintable, thermoplastic polymer blends are prepared from (A) at least about 50 weight percent polyethylene, for example, high density polyethylene (HDPE), grafted with at least about 0.01 weight percent of an unsaturated organic compound, for example, maleic anhydride, and (B) a thermoplastic polymer containing polar groups, for example, a polyurethane or a polyester. Optionally, the grafted polyethylene of (A) can be diluted with an ungrated polyethylene, for example, ungrafted HDPE. These blends can be molded into various structural components, for example, automobile parts, and can be painted without the use of either a primer or a preliminary surface treatment, for example, chemical etching. The polyethylene blends also demonstrate excellent adhesion to various rigid polyurethane foams.
