Abstract

The macromolecular copolymer coupling agent was obtained by free radical solution polymerization using polyalkylene glycol allyl glycidyl ether (AEPH) and vinyl silane coupling agent (A-151) as reacting monomers. The effects of reaction temperature, reaction time and raw material types to the yield of products have been discussed. The structure of the copolymer coupling agent was characterized by Fourier transform infrared spectroscopy and the solubility in water was also investigated. The results show that the copolymer was prepared when the mole radio of AEPH:A-151:BPO was 1:1:1 × 10-3, reaction temperature was 80 ºC and reaction time was 2 h. The hydrolyzate of copolymer could form a transparent water solution. Effect of the copolymer on the bend strength of glass fiber/epoxy composite was also investigated. Compared with the sample of A-151, the bend strength of glass fiber/epoxy composite using the copolymer coupling agent was increased 6.5 %.
