In order to evaluate the gelation behavior of macromonomeric azoinitiators (MIMs), the free radical polymerization of MIM and macrocrosslinkers (MCRs) have been compared. MIMs were synthesized by the reaction between 4,49-dicyano-4,49-azovaleryl chloride and poly(ethylene glycol)s PEG-400, -1000, -1500, -2000 and 4-vinylbenzyl chloride. MCRs were obtained by vinylation of both hydroxyl ends of ...

Front Cover: Caffeic acid is a component of coffee beans and bears catechol functionality. In article number 2100378 by Kotaro Satoh co-workers, caffeic acid-derived styrene monomer amenable to RAFT polymerization, which one the emerging methodologies for polymer synthesis. Combined with protection/deprotection processes, polymerization results in welldefined functional block copolymers consist...

OBJECTIVE To review the epidemiologic literature on styrene and cancer. METHODS We reviewed studies of workers exposed to styrene in manufacturing and polymerization, in the reinforced plastics industry, and in styrene-butadiene rubber production. We also reviewed studies of workers monitored for styrene exposure, studies of environmental exposure, community-based case-control studies of lymp...

ionomers are generally described by copolymers having either acrylic or methacylic acid as one component and the other component is mostly either ethylene or styrene. the objective of this research was to study the thermal behaviour and stability of ionomers of styrene with some alkali metal acrylates. these materials have been synthesized by neutralization of the respective copolymer containin...
