<p>A novel copolymer comprising (a) repeating units of the formula:
<Chemistry id="chema01" num="0001"><Image id="ia01" he="7" wi="78" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>or
<Chemistry id="chema02" num="0002"><Image id="ia02" he="5" wi="79" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R<Sub>f</Sub> is C<Sub>3</Sub>-C<Sub>21</Sub> perfluoroalkyl and p is an interger of 1 to 10 and (b) repeating units of the formula:
<Chemistry id="chema03" num="0003"><Image id="ia03" he="7" wi="77" file="IMGA0003.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein m is an integer of 1 to 4 and n is an integer of 2 to 10 when m is 1, an integer of 1 to 8 when m is 2 or an integer of 0 to (12-2m) when m is 3 or 4,
<Chemistry id="chema04" num="0004"><Image id="ia04" he="9" wi="78" file="IMGA0004.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R' and R<Sup>2</Sup> are each hydrogen, CH<Sub>3</Sub>, CH<Sub>2</Sub>CI, CH<Sub>2</Sub>F, CH<Sub>2</Sub>OCH<Sub>3</Sub>, CH<Sub>2</Sub>OC<Sub>2</Sub>H<Sub>5</Sub>, CH<Sub>2</Sub>OCOCH<Sub>3</Sub>, CH<Sub>2</Sub>OC<Sub>6</Sub>H<Sub>5</Sub>, CH<Sub>2</Sub>OH or CH<Sub>2</Sub>CN provided that at least one of them is not hydrogen,
<Chemistry id="chema05" num="0005"><Image id="ia05" he="8" wi="71" file="IMGA0005.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein q is 2 or 3, and/or
<Chemistry id="chema06" num="0006"><Image id="ia06" he="8" wi="85" file="IMGA0006.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R<Sup>3</Sup> is CH<Sub>2</Sub> or CF<Sub>2</Sub> and r is an integer of 2 to 5, which is particularly useful as a water- and oil-repellent and a non-tackifier.</p> |
