THERMOPLASTIC POLYMER COMPOSITION CONTAINING HYPER-BRANCHED POLYMER AND PRODUCTS MANUFACTURED FROM THIS COMPOSITION Russian patent published in 2008 - IPC C08L77/00 C08L77/10 C08L101/00 

Abstract RU 2318007 C2

FIELD: polymer materials.

SUBSTANCE: invention relates to thermoplastic polymer composition, to products therefrom, and to use of hyper-branched (co)polymer. Composition contains matrix M including at least one thermoplastic(co)polymer and at least one additive, namely, functionalized hyper-branched (co)polymer, which is used as modifier of rheological properties. Functionalized hyper-branched (co)polymer is selected from group consisting of polyesters, polyester-amides, and polyamides. At least 50% of end groups of hyper-branched (co)polymer are functionalized by radical R2, which represents substituted or unsubstituted silicone-type hydrocarbon radical, linear or branched alkyl, aromatic, arylalkyl, alkylaryl, or cycloaliphatic radical optionally incorporating one or several unsaturated bonds and/or one or several heteroatoms. Composition is processed into products via molding, injection casting, injection casting with blowing, extrusion, and spinning.

EFFECT: improved rheological and mechanical properties of composition.
