This article explores current challenges in the use of automated parallel synthesizers in polymeric materials research. Four types of polymerizations were investigated: carbodiimide-mediated polyesterification, diphenol phosgenation, free radical, and reversible addition-fragmentation chain-transfer (RAFT). Synthetic challenges of condensation polymerization, such as liquid and solid dispensing...

This study reports the first attempt to employ a potassium–graphite intercalation compound (KC24) as an initiator for one-pot synthesis of multi-block copolymer. The results obtained show that KC24 successfully initiated copolymerization, leading copolymer consisting poly(styrene), poly(methyl methacrylate) and poly(ethylene oxide) blocks. When all three comonomers were introduced simultaneousl...

Branched and crosslinked degradable polyesters based on lactic acid, lactide and εcaprolactone were prepared by utilizing different polymerization methods. Chain linking of hydroxyl telechelic lactic acid oligomers with 1,6-hexamethylene diisocyanate (HMDI) as a chain extender, yielded lactic acid based poly(ester-urethanes). When an excess of HMDI was used, polymers with broader molecular weig...

In this study, a hydrogel composed of acrylamide (AAm) with N-vinylimidazole (NVI) as co-monomer, with a cross-linker such as N, N` Methylenebisacrylamide and potassium peroxodisulfate as an initiator solution was prepared. Poly (AAm/NVI) hydrogels were synthesized by free radical solution polymerization. Swelling experiments were performed in water at 25°C, gravimetrically. Here, it was of...
