Notes:
A number of polymers of acrylates of fluorine-containing ether alcohols were prepared and studied. The side-chain structures investigated are: CF3CH2OCH2CH2OCO, CF2HCF2OCH2CH2OCO, CF2HCF2(OCH2CH2)2OCO—, CF3CF2CF2CH2OCH2CH2OCO, and RfOCF2CF2CH2OCO—, where Rf equals CF3, CF3CF2, CF3CF2CF2, and CF3CF2CF2CF2—. Of these, the last group has glass transition and stiffening temperatures 20-25°C. lower than those of most of the others, together with the small swelling in solvents characteristic of the RfCH2OCO— series. It is concluded that polymer behavior, particularly the modulus-temperature and solubility characteristics, may be very profoundly affected by the nature of the side chains. An interpretation of the behavior of the polyacrylates of the fluorinated ether-alcohols in terms of increased side-chain flexibility due to ether “swivel joints” is attractive, but may not be justified.
