Abstract
A chlorine-containing resin composition comprising a chlorine-containing resin and at least one calcium compound selected from the group consisting of 2CaO.SiO.sub.2, 3CaO.SiO.sub.2, 3CaO.2SiO.sub.2, the above enumerated compound(s) having coated thereon an organic silicon compound, CaO.TiO.sub.2, 2CaO.TiO.sub.2, 3CaO.TiO.sub.2, CaO.Al.sub.2 O.sub.3, 2CaO.Al.sub.2 O.sub.3, 3CaO.Al.sub.2 O.sub.3, CaAl.sub.2 O.sub.4, CaB.sub.2 O.sub.6, Ca.sub.7 MgAl.sub.10 O.sub.23, CaNb.sub.2 O.sub.6, CaTa.sub.2 O.sub.6, CaTiO.sub.3, CaZrO.sub.3 and CaZrTi.sub.2 O.sub.7. The chlorine-containing resin composition may further comprise an organic acid salt and/or an organic tin compound.
