  The quantization properties of composite peripheric twists are studied.
Peripheric chains of extended twists are constructed for U(sl(N)) in order to
obtain composite twists with sufficiently large carrier subalgebras. It is
proved that the peripheric chains can be enlarged with additional Reshetikhin
and Jordanian factors. This provides the possibility to construct new solutions
to Drinfeld equations and, thus, to quantize new sets of Lie-Poisson
structures. When the Jordanian additional factors are used the carrier algebras
of the enlarged peripheric chains are transformed into algebras of motion of
the form G_{JB}^{P}={G}_{H}\vdash {G}_{P}. The factor algebra G_{H} is a direct
sum of Borel and contracted Borel subalgebras of lower dimensions. The
corresponding omega--form is a coboundary. The enlarged peripheric chains
F_{JB}^{P} represent the twists that contain operators external with respect to
the Lie-Poisson structure. The properties of new twists are illustrated by
quantizing r-matrices for the algebras U(sl(3)), U(sl(4)) and U(sl(7)).
