Title:
BALLOONS MADE FROM LIQUID CRYSTAL POLYMER BLENDS
Document Type and Number:
WIPO Patent Application WO1999012586
Kind Code:
A3
Abstract:
Balloons for use on medical devices such as catheter ballons are formed from polymer blend products which include a liquid crystal polymer (LCP), a crystallizable thermoplastic polymer, especially thermoplastic polyesters such as PET, and a compatabilizer. The compatabilizer my be an ethylene-maleic anhydride copolymer, an ethylene-methyl acrylate copolymer, an ethylene-methyl acrylate copolymer, an ethylene-methyl acrylate-maleic anhydride terpolymer, an ethylene-methyl-methacrylic acid terpolymer, an acrylic rubber, and ethylene-ethyl acrylate-glycidyl methacrylate terpolymer or a mixture of two or more such polymers.
