In this paper, Grubbs- and Hoveyda–Grubbs-type olefin metathesis catalysts featuring N-cyclopentyl/N’-mesityl backbone-substituted N-heterocyclic carbene (NHC) ligands were synthesized. Their propensity to promote the alternating ring-opening copolymerization (ROMP) of norbornene (NBE) with cyclooctene (COE) or cyclopentene (CPE) was evaluated compared that shown by analogous N-cyclohexyl compl...

We report a combined multivariate linear regression (MLR) and density functional theory (DFT) approach for predicting the comonomer incorporation rate in copolymerization of ethene with 1-olefins. The MLR model was trained to correlate set 19 experimental group 4 catalysts steric electronic features dichloride catalyst precursors. Although assembled data were produced different laboratories bot...

Inverse vulcanization is a potential route to the use of large excesses elemental sulfur, creating high-sulfur-content polymers with many applications. The addition metal diethyldithiocarbamate catalyst was previously found bring several benefits inverse vulcanization, making process more attractive industrially. Herein reported establishment and exploration library catalysts for vulcanization....

Abstract The substituted aromatic amine o -toluidine (2-methylaniline, 1-amino-2-methylbenzene) is frequently encountered in electrochemical research as a soluble corrosion inhibitor dissolved aqueous media used e.g., cooling systems, homomonomer for formation of intrinsically conducting poly- and comonomer respective copolymers their composites. obtained polymers are suggested protection coati...

The deconvolution of the molecular weight distribution (MWD) polyolefins into Schultz–Flory most probable distributions has become standard method to identify number site types on multiple-site-type olefin polymerization catalysts such as Ziegler–Natta, Phillips, and some supported metallocenes. This been used quantify effect conditions catalyst formulations polyolefin MWD kinetics. Related met...

Cellulose nanocrystals (CNCs) show promise for enhancing properties of waterborne latexes and coatings. Miniemulsion polymerization is a promising route to obtaining well-controlled latex distributions sufficient encapsulate CNCs in the monomer phase. Here, we demonstrate first miniemulsion resulting encapsulation that incorporates costabilizer, water soluble initiator, comonomer mixtures, aspe...

We report a new aqueous polymerization-induced self-assembly (PISA) formulation that enables the hydrophobic block to be prepared first when targeting diblock copolymer nano-objects. This counter-intuitive reverse sequence approach uses an ionic reversible addition–fragmentation chain transfer (RAFT) agent for RAFT dispersion polymerization of 2-hydroxypropyl methacrylate (HPMA) produce charge-...
