Abstract: THERMOPLASTIC COMPOSITION FOR THE MANUFACTURE OF MEDICAL APPARATUSES AND INSTRUMENTS of the disclosure: The invention relates to a thermoplastic composition for the manufacture of medical apparatuses and instruments, which come into contact with parenteral liquids. This composition consists of from 50 to 99.5 parts by weight of a chlorinated polyolefin having a chlorine content of from 15 to 45 % by weight and an average molecular weight of from 30,000 to 300,000 and of from 0.5 to 50 parts by weight of polymers of acrylic and/or methacrylic acid esters. The receptacles prepared have a low permeability for gases and microorganisms. Their water vapor permeability is also low, but may be adjusted within definite limits.

Abstract: Thermoplastic compsns. for mfg. medical equipment coming into contact with parenteral fluids consist of 50-95 (70-90) pts. wt. chlorinated polyolefin, (I) contg. 15-45 (25-40) wt % Cl and having an average mol. wt. 30000-30,000 (40,000-100,000) and of 5-50 (10-30) pts. wt. acrylate and/or methacrylate ester polymers (II). The compsns. may be prepd. by mixing (I) and (II), but better transparency and uniformity is achieved by polymerising the acrylate and/or methacrylate esters, or their mixts. in the presence of (I). The compsns. are pref. used for making containers for blood or blood substs. infusion equipment or parts, e.g. hoses, catheters etc. and bags for parenteral fluids. The compsn. have low water vapour permeability, high transparency, strength, and weldability and contain no extractable or hydrolysable components.
