Inorganic filler dispersion stabilizer, inorganic filler-containing resin composition, molded article, and additive

An inorganic filler-containing resin composition comprising a resin, an inorganic filler, and an inorganic filler dispersion stabilizer,

• wherein the resin is one or more selected from the group consisting of polyolefin, polyester, polysulfide, polyvinyl chloride, modified polysulfide, silicone resin, modified silicone resin, acrylic urethane resin, epoxy resin, polyurethane, acrylic resin, polyester, and unsaturated polyester;
• and
• the inorganic filler dispersion stabilizer which is a polyester represented by the following general formula (1):
• wherein A1 is an aliphatic dibasic acid residue having 2 to 12 carbon atoms;
• A2 and A3 are each independently an aliphatic polybasic acid residue having 2 to 12 carbon atoms or an aromatic polybasic acid residue having 6 to 15 carbon atoms;
• G1 and G2 are each independently an aliphatic diol residue having 2 to 9 carbon atoms;
• m represents the number of repetitions and is an integer in a range of 1 to 20;
• p is an integer obtained by subtracting one from the number of basic acid functional groups of the aliphatic polybasic acid or the aromatic polybasic acid of A2;
• q is an integer obtained by subtracting one from the number of basic acid functional groups of the aliphatic polybasic acid or the aromatic polybasic acid of A3;
• and A1 and G1 may be the same or different for each repeating unit enclosed in parentheses.
