| 摘要 |
<p>A low molecular weight hair spray resin containing a vinyl monomer having a-
<Chemistry id="chema01" num="0001"><Image id="ia01" he="9" wi="5" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>electron with-drawing group and consisting essentially of alternating units of vinyl ester and an alkyl half ester maleate derived from an alternating vinyl ester/maleic anhydride copolymer. The resins of this invention are defined by the structure:
<Chemistry id="chema02" num="0002"><Image id="ia02" he="46" wi="69" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R and R<Sub>1</Sub> are each independently alkyl having from 1 to 6 carbon atoms and n has a value between about 40 and 250, preferably 60 to 220.</p> |
