Mjm. Abadie et al., PHOTOACTIVE POLYSILOXANES - 3 SYNTHESIS AND PHOTO-CROSS-LINKING OF VINYL-TERMINATED POLYDIMETHYLSILOXANES, Revue Roumaine de Chimie, 42(9), 1997, pp. 923-931
Vinyl-terminated polydimethylsiloxanes of different molecular weights
were prepared by cationic polymerization of octamethylcyclotetrasiloxa
ne in the presence of 1,3-divinyl-1,1,3,3-tetramethyldisiloxan (end bl
ocker). The photoactive behaviour in both inert (N-2) and oxygen conta
ining atmosphere (air) was investigated by differential scanning photo
calorimetry (DSPC). Two photoinitiators (Darocur(R) 1173 and TEPO) wer
e used to promote the radical polymerization of vinyl groups.
