Abstract
The invention provides a thiocyano compound and also provides a three-component sequence-controllable high-molecular compound which is obtained by polymerization reaction of the thiocyano compound monomer, and free radical homopolymerization reaction is carried out on the high-allylic-position thiocyano compound monomer to obtain the high-molecular compound. Active secondary carbon free radicals or tertiary carbon free radicals with relatively large steric hindrance can be rearranged to sulfur atoms in a cyano migration manner, and then attacks a next monomer to carry out chain growth, so that a series of high-molecular compounds with alternating A, B and C components are obtained; the invention also provides application of the three-component sequence-controllable high-molecular compound in the field of high-molecular materials.
