  Synthesis and characterization of some organosilicon derivatives of poly 2-hydroxyethyl methacrylate with cubane as a cross-linking agent

  摘要：

  Some silyl ether derivatives of 2-hydroxyethyl methacrylate (HEMA) were prepared. The Et3Si, Ph3Si and Me3Si groups together with cubane-1,4-dicarboxylic acid (CDA) were covalently linked with HEMA. The silyl-linked HEMA are abbreviated as TETMA, TPhMA and TMEMA, respectively. CDA linked to two HEMA groups is the cross-linking agent (CA). Free radical copolymerization and cross-linking copolymerization of the resulting monomers with 2-hydroxyethyl methacrylate (HEMA) with the various ratios of CA as cross-linking agent, were carried Out using AIBN as initiator at the temperature ranges 60-70 degrees C. The cross-linking copolymers were identified by FT-IR spectroscopy. The glass transition temperature (T-g) of the network polymers was determined calorimetrically. The T, of network polymers increases with increase of cross-linking degree. All monomers and polymers were identified by spectroscopic methods. These silyl derivatives modified methacrylate polymer properties. (c) 2005 Elsevier B.V. All rights reserved.
