Pressure-induced structural change of intermediate-range order in poly(4-methyl-1-pentene) melt.
Phys. Rev. E. Stat. Nonlin. Soft Matter Phys. 85(2 Pt 1) , 021807, (2012) High-pressure in situ x-ray diffraction and specific-volume measurements on isotactic poly(4-methyl-1-pentene) melt have uncovered abrupt changes in the pressure dependence of microscopic structure as well as that of macroscopic density. The first sharp diffr... |

Plasma-induced graft copolymerization of HEMA onto silicone rubber and TPX film improving rabbit corneal epithelial cell attachment and growth.
Biomaterials 15(3) , 163-71, (1994) A poly(2-hydroxyethyl methacrylate) (pHEMA)-grafted polymer film was prepared by plasma-induced graft copolymerization onto an elastic material, silicone rubber, and a plastic material, poly(4-methyl-1-pentene) (TPX). The control, Ar plasma-treated and pHEMA-... |

Application of asymmetric TPX membranes to transdermal delivery of nitroglycerin.
J. Control. Release 50(1-3) , 187-95, (1998) In this study, asymmetric poly(4-methyl-1-pentene) (TPX) membranes, fabricated by the dry/wet inversion method, were applied to transdermal delivery of nitroglycerin (NTG), a drug for treating angina pectoris. The flux of NTG through the TPX membrane was meas... |

Transdermal delivery of triprolidine using TPX polymer membrane.
Int. J. Pharm. 235(1-2) , 141-7, (2002) Triprolidine-containing matrix was fabricated with poly(4-methyl-1-pentene) (TPX) polymer to control the release of the drug. Effect of penetration enhancer and stripping of skin on the permeation of triprolidine through the excised mouse skin was studied. Pe... |

Application of TPX polymer membranes for the controlled release of triprolidine.
Int. J. Pharm. 232(1-2) , 131-7, (2002) Oral administration of triprolidine, antihistamines, may cause many adverse effects such as dry mouth, sedation, dizziness and transdermal drug delivery was considered. Poly(4-methyl-1-pentene) (TPX) membrane, which has good mechanical strength was fabricated... |

Enhanced bioavailability of triprolidine from the transdermal TPX matrix system in rabbits.
Int. J. Pharm. 234(1-2) , 67-73, (2002) The pharmacokinetics and bioavailability of triprolidine, antihistamines, were studied to determine the feasibility of enhanced transdemal delivery of triprolidine from the poly(4-methyl-1-pentene) (TPX) matrix system containing polyoxyethylene-2-oleyl ether ... |

Dispersion of single-walled carbon nanotubes in a non-polar polymer, poly(4-methyl-1-pentene).
J. Nanosci. Nanotechnol. 6(8) , 2520-4, (2006) Poly(4-methyl-1-pentene), PMP, a high melting polymer composed of hydrogen and carbon, has the potential to become an alternative to polyethylene (PE) as shielding material against Galactic Cosmic Radiation (GCR). PMP exhibits higher thermal stability than PE... |

Elimination of sevoflurane is reduced in plasma-tight compared to conventional membrane oxygenators.
Eur. J. Anaesthesiol. 25(2) , 152-7, (2008) It has been demonstrated that volatile anaesthetics have cardioprotective properties during open-heart procedures, especially when administered continuously. European Council Directive 93/42/EEC concerning medical devices bans the supplementary incorporation ... |
