Abstract
The invention provides a polymer composition comprising (i) an LDPE; (ii) a polypropylene; (iii) polyolefin (A) comprising epoxy groups; and (iii) polyolefin (B) comprising carboxylic acid groups and/or precursor thereof.
Claims23
A polymer composition comprising:
- (i) an LDPE in an amount of 40 to 85 wt %, relative to the total weight of the polymer composition;
- (ii) a polypropylene in an amount of 5 to 45 wt %, relative to the total weight of the polymer composition;
- (iii) polyolefin (A) comprising epoxy groups;
- and
- (iv) polyolefin (B) comprising carboxylic acid groups and/or precursor thereof;
- wherein one of polyolefin (A) and polyolefin (B) is a polyethylene and wherein polyolefin (A) and/or polyolefin (B) are each present in an amount of 1.0 to 10.0 wt %, relative to the total weight of the polymer composition;
- wherein the LDPE (i) is not crosslinked and the polypropylene (ii) is not crosslinked;
- and
- wherein the composition consists of LDPE (i), polypropylene (ii), polyolefin (A), and polyolefin (B) as the only polymer components.
