The controlled cationic copolymerizations of isobutylene (IB) with alkenyl styrenes including 4-allylstyrene, p-(3-butenyl)-styrene and p-(5-hexenyl)-styrene were carried out in n-hexane/CH2Cl2 (6/4 v/v) at −80 °C using a t-BuCl/FeCl3/iPrOH initiating system.
The oligomerization of 1-hexene under argon plasma was investigated in a gas–liquid, continuous flow microreactor.
A novel low-k material (Dk is as low as 2.23) was prepared from functionalized 4-tert-butylcalix[4]arene with different numbers of benzocyclobutene (BCB) units (2 or 4) and spacers (–(CH2)3– or –(CH2)6–).
The granular alterations and microstructural disruption associated with high hydrostatic pressure-induced gelatinisation of starches in cassava flour reduced its ability to bind volatiles but it remained stable during storage.
Experimental and theoretical rate coefficients for unimolecular reactions of gas-phase unsaturated organic peroxy radicals (RO2) are in excellent agreement. But the observed products question their contributions to autoxidation in Earth’s atmosphere.
