A novel vinylbiphenyl monomer, 2-methoxyphenylstyrene (MOPS), was designed and efficiently synthesized to investigate the stereospecific polymerization of bulky and polar styrenic derivative. Regardless of its large side group and electron-donating o-methoxy substituent, this compound showed a high polymerizability and was readily converted to the corresponding . Two poly(3-hexylthiophene) (P3HT) macromers containing a donor polymer with a polymerizable methacrylate (MA) end group, P3HT-CH2-MA and P3HT-(CH2)2-MA, have been synthesized, and P3HT-(CH2)2-MA has been successfully homopolymerized and copolymerized with methyl methacrylate (MMA) into stereoregular brush polymers and graft copolymers, respectively, Cited by: 5.

Stereoregular Polymers and Stereospecific Polymerizations Edited by Giulio Natta and Ferdinando Danusso. (The Contributions of Giulio Natta and his School of Polymer Chemistry.) Vol. 1: Pp. xxii Author: C. Bawn. This chapter deals with the generalities on Ziegler–Natta catalysts. Next to the definitions of regular and stereoregular polymers, the discovery of the processes for polymerization of ethylene and stereospecific polymerization are given.
Important for that discovery is the supported catalysts and homogeneous stereospecific catalysts. stereoregular polymer[¦sterēə′regyələr ′pälimər] (organic chemistry) stereospecific polymer Stereoregular Polymer (also stereospecific polymer), any one of the polymers whose linear molecules consists of monomeric units having either identical spatial configurations or configurations that, while not identical, alternate in regular.
Other articles where Stereoregular polymer is discussed: catalysis: Catalysis in stereoregular polymerization: The importance of the concept of adsorption of reactants on the surface of catalysts has been greatly increased by the development of stereoregular polymerization processes—that is, methods that yield polymers whose molecules have definite three.
Recent advances in controlled polymerizations, including living and stereospecific polymerizations, as well as highly efficient reactions, such as click reactions, enable the synthesis of various architecturally controlled polymers .In addition, an alternative and more efficient synthetic route for polymer structures can be created by these developments, which is the Cited by: 1.
IUPAC recommendations have defined stereospecific polymerization and related terms as follows [1, 2, 3]: “Stereospecific polymerization is polymerization in which a tactic polymer is polymer is composed of tactic macromolecules. Tacticity (from Greek τακτικός taktikos "of or relating to arrangement or order") is the relative stereochemistry of adjacent chiral centers within a macromolecule.
The practical significance of tacticity rests on the effects on the physical properties of the regularity of the macromolecular structure influences the degree to which it has rigid, crystalline long range. Next to the definitions of regular and stereoregular polymers, the discovery of the processes for polymerization of ethylene and stereospecific polymerization are given.
The intent of that protective metal structure was to prevent the traffic of the numerous, the rather pied (though mainly in shades of gray) and disorganized tribe of the students irresistibly tempted to abridge their way from the bus station from Witting by penetrating fraudulently into the sacred area of the research on the stereospecific polymerization of isoprene rubber.

The Rh-mediated polymerization of carbenes gives access to new highly substituted, stereoregular polymers. Detailed end-group analysis, dilution-kinetic studies, and catalyst variation unveil the mechanisms of chain-initiation, chain-termination, and chain-transfer processes during the polymerization process, and shed new light on the multistep Cited by: Free-radical polymerization (FRP) is a method of polymerization by which a polymer forms by the successive addition of free-radical building blocks.
Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules. Following its generation, the initiating free radical adds (nonradical) monomer units, thereby growing the polymer chain.
stereospecific polymer (plural stereospecific polymers) A polymer that has a specific spatial arrangements of its constituent atoms, leading to an almost crystalline structure; Synonyms. stereoregular polymer.Stereospecific Catalytic Polymerization of α-Olefins α-olefins are often polymerized in the presence of stereospecific catalysts such as metallocenes or Ziegler-Natta catalysts.
