Abstract

Using gamma-radiation as initiation source at ambient temperatures (i.e. T approximate to 20 degreesC) for reversible addition-fragmentation chain transfer (RAFT) polymerizations allows for the generation of narrowly distributed polymeric material with living characteristics. It is shown that the living characteristics effected by RAFT agent mediated bulk polymerizations using gamma-irradiation are associated with a RAFT mechanism rather than with reversible termination processes. Furthermore, gamma-radiation as initiation source for an appropriate RAFT agent/monomer system allows for effective radical storage and the generation of long-lived reaction intermediates at ambient temperatures. The current overview further demonstrates how the RAFT process together with gamma-radiation as source of initiation can be employed to graft various monomers onto polypropylene surfaces in a controlled manner.

89 citations in Web of Science®

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
