of medical plastic products such as tubing, drip chambers,
injection reseal devices and other parenteral administration
equipment. Additionally, Hillier intimates that the disclosed
composition will have low alkaline extraction values so that
ingredients in the composition are not extracted into the
fluids to be administered. See col. 1, lines 7-42.
Kobayashi discloses a polyester type copolymer
composition comprising a polyester ether mixed with a
copolymer of ethylene with methacrylic acid neutralized with a
metallic ion to a methacrylate salt (col. 1, lines 33-40; col.
3, lines 22-43). The resulting composition has greatly
improved moldability, mechanical characteristics (strength,
elongation and frictional characteristics), heat resistance
and transparency (col. 5, lines 1-13). Consequently,
according to Kobayashi, the composition can be used for
various utilities, such as injection moldings, blow moldings
and extrusion moldings useful as parts of various machines
(e.g., name plates, automobile parts, switches, holders,
hooks, packings, etc.), coatings and the like (col. 5, lines
14-19).
