Some Properties of Fluorine-containing Polyalkyl meth acrylates and a-fluoroacrylates

4 Some Properties of Fluorine-containing Polyalkyl(meth)acrylates and a-fluoroacrylates 

Structure, length of hydrocarbon chain, location [26] and amount of fluorine atoms in fluoroalkyl radical significantly affect properties of appropriate methacrylic polymer (see Table 8.9). Increasing the content of fluorine atoms in the polymer, increases the chemoresistance, thermo- and heat resistance and water absorption decreases. It should be noted that the fluorine atom in the ro-position in fluoroalkyl radical leads to a decrease of the surface tension, which is also the the reason for poor adhesion of the fluorine-containing polymer to the core and water absorption. In the a-position, the heat resistance and other properties of polymers obtained on this basis are presented in Table 8.10 [25].

As the carbonic chain of the alkyl group propagates, of the polymer decreases. For fluorinated polymers, is 30 °C higher than for non-fluorinated analogues.
