Yen-Ching Chiang,Alex M. Jamieson,Sandi Campbell,Yuhui Lin,Neil O'Sidocky,Liang-Chy Chien,M. Kawasumi,Virgil Percec +7 more
TL;DR: In this article, the electro-rheological (ER) response of liquid crystal polymer (LCP) solvents with positive dielectric anisotropy was investigated.
Journal ArticleDOI
Phase identification in a series of liquid-crystalline TPP polyethers and copolyethers having highly ordered mesophase structures. 4. Phase structures and order evolution in TPP(n = 12) thin films
TL;DR: In this paper, a main-chain liquid-crystalline polyether has been synthesized from 1-(4-hydroxy-4'-biphenylyl)-2-(4hydroxyphenyl)propane and 1,12-dibromododecane, TPP(n = 12).
Patent
Living radical polymerization of halogen-containing and acrylic monomers and the formation of block copolymers therefrom
TL;DR: In this article, a living radical polymerization of acrylic polymers using organo-halide initiators with either metal-free or metal catalysts is described, and a block copolymer of either the vinyl halide monomers or acrylic monomers is described.
Journal ArticleDOI
Ultrafast SET-LRP with Peptoid Cytostatic Drugs as Monofunctional and Bifunctional Initiators.
TL;DR: It is reported that stable 2-bromopropionyl peptoid-type initiators such as 1,4-bis(2- bromoprostionyl)piperazine and 4-(2-bROMopropianyl)morpholine are an alternative that meets the standards reached by the well-known secondary and tertiary α-haloester- type initiators in terms of excellent control over molecular weight evolution and distribution as well as polymer chain ends.
Journal ArticleDOI
Phase Identification in a Series of Liquid Crystalline TPP Polyethers and Copolyethers Having Highly Ordered Mesophase Structures. 8. Phase and Structural Evolution in a Series of Copolyethers Containing Odd-Numbered Methylene Units in Both Comonomers

TL;DR: In this paper, a series of liquid crystalline copolyethers have been synthesized from 1-(4-hydroxy-4'biphenyl)-2-(4hydroxyphenyl)propane with 1,7-dibromoheptane and 1,11-diamoundecane (coTPPs-7/11).
