摘要： Unsaturated polyester resins having improved fire retardant properties comprise a halogen-containing unsaturated polyester of a polycarboxylic compound and a polyhydric alcohol together with an additive mixture comprising iron or a compound of iron and at least one member of the group consisting of copper, a compound of copper, antimony and a compound of antimony. The unsaturated polyester resin may be copolymerized with an unsaturated monomer to prepare castings, laminated products, reinforced articles and the like having low burning rates, low smoke generation, and beneficial char formation in the presence of a flame.

摘要： Highly fire retardant unsaturated polyester resins which exhibit low burning rates, low smoke generation and beneficial char formation in the presence of a flame are provided by incorporating up to about 5 weight percent of copper or a copper compound in a halogen containing unsaturated polyester of a polycarboxylic compound and a polyhydric alcohol having greater than about 4 weight percent halogen based on the weight of unsaturated polyester resin and a copolymerizable unsaturated monomer. The unsaturated polyester resins are copolymerized with an unsaturated monomer for use in castings, laminated products and other reinforced articles.

摘要： Fire retardant polymer compositions having improved smoke-retardance are prepared from:(1) a copolymerizable mixture of:(a) from about 50 to 80 weight percent of an .alpha.-,.beta.-, ethylenically unsaturated halogen-containing polyester of a polycarboxylic compound and a polyhydric alcohol, the polyester containing halogen in a proportion of greater than about 4 weight percent said halogen having been introduced subsequent to preparation of the polyester by esterification; and(b) from about 20 to about 50 weight percent of a mixture of unsaturated monomers comprising a vinylbenzene compound and an acrylic compound selected from the group consisting of acrylic acid, methacrylic acid and esters of these acids, the weight ratio of vinylbenzene compound to acrylic compound being about 1:4 to 4:1; and(2) an effective fire retardant proportion of about 0.5 to about 10 weight percent of a smoke inhibiting additive comprising at least 0.5 weight percent of a compound of iron as the sole fire retardant additive or as a component of an additive mixture of an iron compound and an antimony compound and/or a copper compound.

摘要： Polymerizable polyester compositions are provided containing a styrene-maleic anhydride copolymer reacted with a hydroxyl terminated saturated polyester. Such compositions have good thickening response and are free from tackiness in the uncured state, and upon curing have good shrinkage control and improved surface smoothness. The compositions are useful as bulk molding compounds or sheet molding compounds.
