Polymer miscibility modifiers

A brief description of the process

The method to produce the modifiers comprises joining selected small-molecular compounds or oligomers (hydrocarbon resins) to macromolecules of polypropylene, polyethylene or block (SIS / SBS) co-polymers. The reaction is performed in alloy. The process is waste-free.

Advantages of the technology offered

Obtained modifiers, due to the presence of reactive groups in macromolecules, more favorably interact with constituents of polymeric compositions, influence morphology of the compositions and stabilize their phase structure. Therefore it is possible to obtain „tailor-made” materials.


Heated agitators with sigma type stirrers or extruders (most favorably twin-screw).

Advancement of proceedings

Laboratory works have been completed.

Patent PL 209959 (2011) „Method to produce polystyrene impact modifiers and modified low-impact polystyrene”.

Market competitiveness

The modifiers are new products of diversified chemical construction, and hence they have a wide spectrum of applications in mixtures of various polymers. Moreover they can be based on both primary and secondary waste polymers.
