    摘要: Uncured, curable, unsaturated polyester resin compositions consisting essentially of an unsaturated polyester, an ethylenically unsaturated monomer such as styrene or a similar monomer inhibited with about 0.1-1.5 mole percent of 2nitroresorcinol having shelf lives in excess of about 100 days at about 70* C.

    摘要: A CURABLE LIQUID COMPOSITION CONSISTING ESSENTIALLY OF: (A) A POLYENE HAVING THE FORMULA

    (CH2=CH-CH2)2-N-CH2-CH(-OH)-CH2-AN-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-PHENYLENE)-C(-CH3)2-(1,4-PHENYLENE)-O-CH2-CH(-OH)-

    CH2-

    AND N IS ESSENTIALLY 0 OR GREATER (E.G.,0-20), (B) A POLYTHIOL, THE EQUIVALET RATIO OF POLYENE TO POLYTHIOL BEING AOUT 1:0.5-1.5, AND (C) A MEMBER SELECTED FROM A GROUP CONSISTING OF A MONOMERIC ACID HAVING THE FORMULA

    CH2=C(-R)-COOH

    WHERE R IS H, CH3, OR C2H5 OR A HOMPOLYMER OF 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 COMPOSITON CAN CONTAIN AN EFFECTIVE AMOUNT OF A PHOTOCURING RATE ACCELERATORR.
