	Process for the preparation of large surface area, finely divided precipitated calcium carbonate and filled polymeric ...
		A filled polyvinylchloride polymer composition which comprises polyvinylchloride; about 9 phr of impact modifier; and about 4 phr of precipitated calcium carbonate having an average specific surface area of from about 75 m.sup.2 /g to about 85 m.sup.2 /g and having a coating thereon derived from a salt of a fatty acid.
		Such polyvinylchloride polymer compositions filled with the fatty acid derivative coated precipitated calcium carbonate of this invention have enhanced properties of decreased shear stress, increased impact strength and an increased output level of polymer per unit of energy consumption without significantly sacrificing the transparency of the composition.
		Polyvinylchloride formulations were prepared using a medium low molecular weight polyvinylchloride and a basic formulation suitable for bottle applications with 5 phr of impact modifier and various levels of 10% sodium stearate coated precipitated calcium carbonate having a specific surface area before coating of either 22 m.sup.2 /g or 85 m.sup.2 /g.

		These materials have tended to replace the older polyvinylchloride feeding tubes that tend to stiffen when exposed to digestive juices and are more irritating to patients, necessitating frequent tube replacement.
		Polyvinylchloride (Infant Feeding Tube, Argyle Division of Sherwood Medical, St. Louis, MO) or red rubber tubes (Sovereign Feeding Tube, Monoject Division of Sherwood Medical, St. Louis, MO) are the least expensive tubes, although the polyvinylchloride tubes may harden within two weeks of insertion and cause irritation or ulceration of the pharynx or esophagus.
		A 5 French polyvinylchloride tube (Infant Feeding Tube, Argyle Division of Sherwood Medical, St. Louis, MO) is introduced into the bowel lumen through the hypodermic needle and is advanced for 20 to 30 cm aborally.
