Embodiment Construction

[0049] The present invention relates to a kind of polyolefin resin, it comprises:

[0050] Polyolefin A and / or Polyester B; and

[0051] Compatibilizer Blend C.

[0052] The compatibilizer is a blend comprising:

[0053] Functionalized polyolefins containing hydroxyl functional groups,

[0054] polyester, and

[0055] Transesterification products of functionalized polyolefins containing hydroxyl functional groups with polyesters, which may be block copolymers or graft copolymers.

[0056] Preferably, the functionalized polyolefin containing hydroxyl functional groups or a mixture of functionalized polyolefin containing hydroxyl functional groups and unfunctionalized polyolefin is the main polymer in the resin. Therefore, the amount of polyolefin A and / or functionalized polyolefin containing hydroxyl functional groups relative to the resin is preferably greater than the amount of polyester relative to the resin.

[0057] The polyolefin resin is preferably a polypropylene res...

Abstract

The present invention relates to a resin comprising A) a polyolefin, B) a polyester and C) a compatibilizer which is a transesterification product of a functionalized polyolefin containing hydroxyl functional groups and a polyester. The invention also relates to a method for preparing such a resin.

Description

technical field [0001] The present invention relates to polyolefin resins comprising polyolefins and polyesters. The present invention also relates to a method of making such a resin, an article comprising such a resin and the use of such resin for making an article. Background technique [0002] Polyolefins and especially polypropylene homopolymers (PP) are frequently used in structural plastic parts, especially in the automotive industry. The benefits of this material are modulus / impact balance, high surface quality and high chemical resistance to polar organic fluids. [0003] One way to increase the hardness of PP is to apply nucleating / reinforcing agents such as mineral fillers such as talc. However, the application of such agents may erroneously affect high surface quality and impact resistance. [0004] Another approach is to include other engineering plastics / polymers in PP, eg polyesters such as PET, PBT. [0005] In fact, high crystalline engineering plastics l...
