POLYACRYLATES CONTAINING HEXAFLUOROISOPROPOXY PENDANT FUNCTIONS

A series of new polyacrylates was synthesized by incorporating the hex afluoroisopropoxy unit pendant to the backbone. The fluorinated monome rs were synthesized by reacting 4-fluoro(2-hydroxyhexafluoroisopropyl) benzene with acrylic or methacrylic acid chlorides. The polymers were obtained by bulk, free-radical polymerization techniques using alpha,a lpha'-azobisisobutyronitrile as initiator. The polymers had viscositie s ranging from 0.15 to 1.41 dl g-1 and had good film-forming propertie s. Thermogravimetric analysis showed that they had thermal stability u p to 370-degrees-C in N2; glass transition temperatures were in the ra nge 64 to 119-degrees-C.
