The synthesis and some properties of oligo (oxyethylene-urethane methacrylates)

摘要: THE synthesis of high polymers from reactive oligomers has become widespread in recent years. From the technological point view most interesting are polymerizable with unsaturated end groups, which convertible without elimination side products to crosslinked substances molecular weight, length chains between network points is dependent on weight original oligomers. In this connection one pressing problems physical chemistry these find dependence properties nature and size Here first task study their weight. The materials used investigation were oligomers, a,w-bis(4-methacryloxyethylcarbamatotoluylene-2-carbaminic) esters oligo(ethylene) glycols (oligo(oxyethyleneurethane methacrylates)) 670-15,600.
