    摘要： Organic polyphosphites are disclosed having in the molecule at least two phosphite ester groups, at least one of which is linked through oxygen to a phenylethylidene-substituted phenyl group and to a residue of a polyhydroxy compound which is a pentaerythritol residue or a residue of a phenol or alcohol having two to three hydroxyl groups separated from one another by at least three carbon atoms.Polymer stabilizer compositions comprising an organic polyphosphite as disclosed and a known polymer stabilizer, as well as synthetic resin stabilized with such stabilizer compositions, are also disclosed.

    摘要： New polyhydric phenol coesters are disclosed of polyhydric phenols, having 2 to 3 phenolic hydroxyl groups and 1 to 3 benzenoid rings, with carbonic acid and an inorganic acid which can be phosphorous acid, phosphoric acid, and boric acid. The new coesters have molecular weights from 700 to about 10,000, preferably from 1200 to 7000, and are highly effective stabilizers for a variety of synthetic resins.Stabilizer compositions comprising a polyhydric phenol coester and a known polymer stabilizer, as well as synthetic resins stabilized with such stabilizer compositions, are also disclosed.
