Morgan, David L. published the artcileEnd-Quenching of TiCl4-Catalyzed Quasiliving Polyisobutylene with Alkoxybenzenes for Direct Chain End Functionalization, Product Details of C8H9ClO, the main research area is polyisobutylene alkoxybenzene end quenching.
Alkoxybenzenes were used to end-quench TiCl4-catalyzed quasiliving isobutylene polymerizations initiated from 2-chloro-2,2,4-trimethylpentane or 5-tert-butyl-1,3-di(1-chloro-1-methylethyl)benzene at -70 °C in 40/60 (volume/volume) hexane/methyl chloride. The alkoxybenzene/chain end molar ratios were in the range 2.5-4. Effective alkoxybenzene quenchers included those with simple alkyl groups, such as anisole and isopropoxybenzene, haloalkyl tethers, such as (3-bromopropoxy)benzene and (2-chloroethoxy)benzene, and even those with hydroxyl and amine functionality, such as 4-phenoxy-1-butanol and 6-phenoxyhexylamine. Alkylation was generally quant. and occurred exclusively in the para position; multiple alkylations on the same alkoxybenzene were not observed The alkylation reactions were tolerant of temperatures ranging from -70 to -30 °C and were unimpeded by the presence of endo- or exo-olefin termini. In situ cleavage of the ether linkage of anisole and isopropoxybenzene termini allowed single pot syntheses of phenol-terminated polyisobutylenes.
Macromolecules (Washington, DC, United States) published new progress about Polymerization. 622-86-6 belongs to class ethers-buliding-blocks, name is (2-Chloroethoxy)benzene, and the molecular formula is C8H9ClO, Product Details of C8H9ClO.
