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:
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 4,6-DINITRO-O-CRESOL OR 2,4-DINITROANILINE HAVING SHELF LIVES IN EXCESS OF ABOUT 100 DAYS AT ABOUT 70*C.
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.
