Synthesis and characterization of polyisobutylene-b-polyamide multi-block copolymer thermoplastic elastomers
TL;DR: In this article, a series of polyisobutylene (PIB)-polyamide (PA) multi-block copolymers were synthesized via an amidation reaction to form novel thermoplastic elastomers (TPEs).

Direct Chain End Functionalization of Living Polyisobutylene Using Phenoxyalkyl (Meth)acrylates
TL;DR: Phenoxyalkyl acrylates were used as quenching agents for living carbocationic polymerization of isobutylene (IB) at −70 °C in 40/60 (v/v) hexane/methyl chloride, catalyzed by TiCl4 as mentioned in this paper.

NMR and mass spectral analysis of step-growth polymers from azide alkyne cycloaddition and regioselectivity afforded by copper(I) and ruthenium(II) catalysts
TL;DR: In this article, Azide alkyne cycloaddition was applied to step growth polymerization of the diazido monomer, di(3-azido-2-hydroxypropyl) ether of bisphenol-A (DAHP-BPA) with either tetraethyleneglycol dipropargyl ether (TEGDPE) or tetrasenylenedillectric dipropiolate (tEGDP), and the resulting oligomers and polymers were characterized using 1H- and 13C-NMR spectrosc

TL;DR: In this article , two local embedding methods for systematic determination of active spaces are developed and compared for modeling chemical reactions on surfaces with quantum algorithms, and illustrate it for water dissociation on a magnesium surface.
Synthesis and thiol–ene photopolymerization of (meth)allyl-terminated polysulfides
TL;DR: In this paper, the authors performed photopolymerization of equimolar thiol:ene mixtures at 320-500 nm (30 mW/cm2) in the presence of 5 wt % 2,2-dimethoxy-2-phenyl-acetophenone (DMPA).
