Sensitizing effect of polyvinyl monomers on electron beam crosslinking of brominated butyl rubber was written by Xu, Yunshu;Yoshii, Fumio;Makuuchi, Keizo. And the article was included in Huagong Xuebao (Chinese Edition) in 2013.COA of Formula: C16H26O7 This article mentions the following:
Radiation crosslinked product of brominated butyl rubber (BIIR) was achieved by electron beam (EB) irradiation Gelling dose of BIIR was estimated to be 12 kGy. Various polyvinyl monomers were tested to enhance EB crosslinking of BIIR to obtain high crosslinking degree at low dose to avoid main chain degradation under high dose irradiation TMPT (trimethylolpropane trimethacrylate) was the most effective crosslinking sensitizer to increase the crosslink d. of BIIR. The tensile strength of EB crosslinked BIIR was significantly improved by using TMPT as the sensitizer. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1COA of Formula: C16H26O7).
((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.COA of Formula: C16H26O7
