摘要：
THIS INVENTION RELATES TO CROSSLINKABLE POLYMERS HAVING A PLURALITY OF REPEATING UNITS OF THE FORMULA,
-CH2-C(-)(-R)-COOCH2-(CH(-)-CH2(-))(-Y)(-OOC-RD)
WHEREIN R IS H, CH3, CL, OR CN, RDCOO- IS THE RADICAL DERIVED FROM AN UNSATURATED FATTY ACID CONTAINING 16 TO 20 CARBON ATOMS AN CONSISTING OF 1 TO 4 -CH=CHGROUPS, AND Y REPRESENTS -OH, AN ACYLOXY (-OOCR''), OR A URETHANE GROUP (-OOCNHR"), WHEREIN R'' IS HYDROGEN OR AN ALIPHATIC, AROMATIC OR CYCLOALIPHATIC HYDROCARBON RADICAL PREFERABLY OF NO MORE THAN 20 CARBON ATOMS, AND R" IS R'' OR A MONOISOCYANATE DERIVATION OF AN R'' HYDROCARBON RADICAL. THESE NEW POLYMERS BECOME INSOLUBLE ON EXPOSURE TO AIR.
-CH2-C(-)(-R)-COOCH2-(CH(-)-CH2(-))(-Y)(-OOC-RD)
WHEREIN R IS H, CH3, CL, OR CN, RDCOO- IS THE RADICAL DERIVED FROM AN UNSATURATED FATTY ACID CONTAINING 16 TO 20 CARBON ATOMS AN CONSISTING OF 1 TO 4 -CH=CHGROUPS, AND Y REPRESENTS -OH, AN ACYLOXY (-OOCR''), OR A URETHANE GROUP (-OOCNHR"), WHEREIN R'' IS HYDROGEN OR AN ALIPHATIC, AROMATIC OR CYCLOALIPHATIC HYDROCARBON RADICAL PREFERABLY OF NO MORE THAN 20 CARBON ATOMS, AND R" IS R'' OR A MONOISOCYANATE DERIVATION OF AN R'' HYDROCARBON RADICAL. THESE NEW POLYMERS BECOME INSOLUBLE ON EXPOSURE TO AIR.
