Termination by primary radicals in vinyl polymerization

Nonlocal photopolymerization kinetics including multiple termination mechanisms and dark reactions Part I Modeling

“…However, studies have shown [17][18][19] that at high initiation rates the dependence on initiation drops below that predicted by the square root dependence in Eq. (1).…”

“…(1) becomes pronounced. These effects have been attributed to a phenomenon known as primary radical termination, i.e., primary termination [15,[17][18][19]. At these higher initiation rates, there is a significantly larger primary radical concentration, which, as a result, increases the likelihood of primary termination.…”

“…In the analysis presented here the effects of primary radical recombination will be neglected, as it has been shown that these events are negligible when compared with other polymerization kinetic reactions [17,25].…”

Non-local photo-polymerization kinetics including multiple termination mechanisms and dark reactions: Part III Primary radical generation and inhibition

“…In a recent review [29], many of the assumptions made in developing photochemical models of free radical photopolymerization were discussed [1][2][3][4][5][6][7][8][19][20][21][22][23][24][25][26][27][28]. A number of physical effects not included in the previous models were listed, which indicated a lack of physicality under certain exposure conditions.…”

“…Photopolymer materials and the photochemical kinetics associated with them [1][2][3][4][5][6][7][8][9][10] have been studied extensively in both academia and industry due to the growing interest in applications involving photopolymers [11][12][13][14][15][16][17][18]. In order to maximize the potential of these materials for various applications, the necessity for a physically comprehensive theoretical model of the effects which occur during photo-polymerization is becoming ever more important [4,[6][7][8][9][10][19][20][21][22][23][24][25][26][27][28].…”
