The deposition of chlorhexidine base on thermosensitive N-isopropylacrylamide polymeric microparticles was assessed in this study using energy dispersive X-ray spectrometry (EDXS) in scanning electron microscopy (SEM) setting. Three different types of polymer were synthesized. The PN1 was a polymer with terminal anionic groups resulting from potassium persulphate initiator. The PN2 was synthesi...

Crystallization-driven self-assembly of polyethylene-b-poly(tert-butylacrylate) (PE-b-PtBA) block copolymers (BCPs) in N,N-dimethyl formamide (DMF) was studied. It is found that all three PE-b-PtBA BCPs used in this work can self-assemble into one-dimensional crystalline cylindrical micelles. When the BCP solution is cooled to crystallization temperature (Tc) from 130 °C, the seed micelles may ...

The composition of low-Tg n-butylacrylate-block-(acetoxyaceto)ethyl acrylate block polymers is investigated as a strategy to tune the properties dynamically cross-linked vinylogous urethane vitrimers. As proportion cross-linkable increased, thermorheological properties, structure, and stress relaxation evolve in ways that cannot be explained by increasing cross-link density alone. Evidence pres...

The photochemistry of a series of bis(acyl)phosphine oxides and the rate constants of the reactions of their phosphorus radicals with n-butylacrylate, thiophenol, bromotrichloromethane, oxygen, and methyl viologen have been investigated by laser flash photolysis. The results were compared to a mono(acyl)phosphine oxide ((2,4,6-trimethylbenzoyl)diphenylphosphine oxide). The variation in reactivi...
