摘要

A method for determinoffing the molecular mass distribution (MMD) in mixtures of perfluorinated oligomers based on analysis of the differential thermogravimetric (DTG) curves (temperature dependences of the rate of mass loss) is proposed. It is indicated that this method allows us to measure the MMD of oligomers whose boiling temperature is less than the temperature of their thermal decomposition, and the total portion of longer oligomers. This method was applied to the determination of MMD of products of the radiation–chemical telomerization of tetrafluoroethylene in solution.
