✦ Synopsis

Alkylation of phenylacetonitrile by 1-bromobutane with 50% sodium hydroxide and a polymer-supported phase transfer catalyst proceeds fastest when the phenylacetonitrile is added to the mixture before the 1-bromobutane. Alkylation of phenylacetonitrile (PAN) promoted by aqueous sodium hydroxide and quaternary ammonium salts is one of the most widely studied examples of phase transfer catalysis (PTC).'

Polymer-supported phase transfer catalysts with active sites mostly on the surface were prepared by suspension copolymerization of styrene (St), divinylbenzene (DVB), and vinylbenzyl chloride (VBC) with AIBN, followed by the quaternization of the resulting copolymer beads with triethylamine.

## Abstract Pulsed‐laser polymerization (PLP) has been adopted by IUPAC as the method of choice for the determination of propagation rate constants (__k__~p~). However, the method has failed in the polymerization of alkyl acrylates at temperatures above 30 °C. In this work, the PLP experiments were
