摘要:
The invention relates to a method of preparing a fluorinated copolymer, comprising a step of copolymerization of a fluorinated monomer (of the vinylidene fluoride type) with an α-trifluoromethacrylic acid monomer or derivative of α-trifluoromethacrylic acid, in the presence of a xanthate or trithiocarbonate compound. The invention also relates to copolymers obtained by this method as well as block copolymers comprising a copolymer block prepared according to this method.
摘要:
Methods and systems for processing an electromagnetic (EM) band are disclosed, including receiving a digitized EM band comprising two or more channels where two or more of the channels comprise modulated information; receiving two or more selections of two or more of the channels from two or more users; and demodulating the information from the selected channels.
