Aceclofenac-loaded pluronic F108/L81 mixed polymeric micelles: effect of HLB on solubilization Des. Monomers Polym. (IF 1.6) Pub Date : 2022-01-28 M. Senthilkumar, Sasmita Dash, R. Vigneshwari, E. Paulraj
ABSTRACT Pluronic block copolymers have phase behavioural characteristics which are extensively studied for drug delivery applications. In this study, we explored hydrophilic pluronic F108 (HLB = 27), hydrophobic pluronic L81 (HLB = 2) and their mixed micelles acting as solubilising mediums for model drug aceclofenac. The drug solubilisation and interactions have been analysed using UV-visible spectroscopy

Low dielectric resins derived from hyperbranched carbosilane oligmers functionalized by benzocyclobutene groups Des. Monomers Polym. (IF 1.6) Pub Date : 2021-12-09 Xian Li, Yawen Huang, Xu Ye, Quan Long, Wen Yuan, Li Fan, Qiuxia Peng, Jiajun Ma, Junxiao Yang
ABSTRACT Polycarbosilanes have been considered as potential materials used in electronic packaging and circuit boards owing to their excellent low-dielectric performance. In this work, we prepared new hyperbranched carbosilane oligomers (HCBOs) which were functionalized by benzocyclobutene (BCB) groups. HCBOs can be thermally cured to produce transparent (HCBRs) with low dielectric constant and high
