Curable liquid polyene-polythiol compositions containing polyacrylic acid and derivatives thereof
Abstract
Abstract A CURABLE LIQUID COMPOSITION CONSISTING ESSENTIALLY OF; (A) A POLYENE HAVING THE FORMULA (CH2=CH-CH2-)2-N-CH2-CH(-OH)-CH2-(A)N-O-1,4-PHENYLENE- C(-CH3)2-1,4-PHENYLENE-O-CH2-CH(-OH)-CH2-N(-CH2-CH=CH2)2 WHERE A IS -(O-1,4-PHENYENE-C(-CH3)2-1,4-PHENYLENE-O-CH2-CH(OH)-CH2)- AND N IS ESSENTIALLY 0 OR GREATER (E.G., 0-20); AND (B) A POLYTHIOL, THE EQUIVALENT RATIO OF POLYENE TO POLYTHIOL BEING ABOUT 1:0.5-1.5: AND (C) A MEMBER SELECTED FROM A GROUP CONSISTING OF A MONOMERIC ACID HAVING THE FORMULA WHERE R IS H, CH3, OR C2H5 OR A HOMOPOLYMER OR COPOLYMER OF SUCH MONOMERIC ACID HAVING AN AVERAGE MOLECULAR WEIGHT OF ABOUT 140-1000, THE GROUP MEMBER CONSTITUTING ABOUT 2-10% BY WEIGHT OF THE COMPOSITION. THE ABOVE COMPOSITION CAN CONTAIN AN EFFECTIVE AMOUNT OF A PHOTOCURING RATE ACCELERATOR. CH2=C(-R)-COOH
