Regular comb polystyrenes and graft polyisoprene/polystyrene copolymers with double branches (“centipedes”). Quality of (1,3-phenylene) bis (3-methyl-1-phenylpentylidene) dilithium initiator in the presence of polar additives
Abstract
The synthesis of regularly spaced comb polystyrenes and graft polyisoprene/polystyrene copolymers with two branches at each junction point (centipedes) is presented. The synthetic approach involves the selective replacement of two chlorines of SiCl 4 by polystyrene (PS) followed by step−growth polymerization of the produced (PS) 2 SiCl 2 with α,ω-dilithium PS or 1,4 polyisoprene (PI). The polydispersity indices of the reaction products, PS- g -PS 2 (homocentipedes) and PI- g -PS 2 (cocentipedes), varied between 2.0 and 3.0 but was reduced to 1.2−1.3 by fractionation. The quality of (1,3-phenylene)bis(3-methyl-1-phenylpentylidene)dilithium initiator (DLI), used for the synthesis of the dianion, in the presence of polar additives (THF, Et 3 N, and s -BuOLi), was evaluated.

Linking chemistry opens endless possibilities of various molecular architectures, as demonstrated by work of Mays, Hadjichristidis, Hirao, Quirk, and many others through chlorosilane and DPE-based linking chemistry.
“Another advantage of this linking chemistry is that it opens endless possibilities of various molecular architectures [5,42,52,53], as demonstrated by the work of Mays, Hadjichristidis, Hirao, Quirk, and many others through chlorosilane and 1,1-diphenylethylene (DPE)-based linking chemistry (Figure 3).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
