Immobilization of polyisobutene in semi-interpenetrating polymer network architecture 
(5323-5331) Polymer 51 #23 (2010)
Davion et al of the Université de Cergy-Pontoise, France synthesized homogeneous linear PIB/cross-linked polycyclohexylmethacrylate (PCHMA) semi-IPNs containing from 20 to 70 wt% PIB without solvent .  This material shows no cold flow and higher mechanical properties than those of linear PIB or 50 wt% PIB containing blend. In addition, the particular barrier properties toward gas and water are preserved because of the phase co-continuity morphology of the semi-IPN materials.  (RDC 12/17/2010)
