Polymer composition contains a rheology modifier comprising a functionalized, hyperbranched copolyamide obtained by reacting a monomer(s), optionally a spacing monomer, optionally a core monomer and a chain limiting monomer(s) Polymer composition comprises a thermoplastic polymer matrix and a rheology modifier comprising a functionalized, hyperbranched copolyamide obtained by reacting a monomer(s) of formula (I), optionally a spacing monomer of formula (II), optionally a core monomer of formula (III) and a chain limiting monomer(s) of formula (IV), where at least 50% of the terminal groups are functionalized by R2: ARBf (I) A'R'B' (II) R1(B'')n (III) R2A'' (IV) A, A', A'', B, B' and B'' = reactive groups; R and R' = hydrocarbon group; f = at least 2, preferably 2-10; R1 and R2 = hydrocarbon group; and n = at least 1, preferably 1-100. |
