| 摘要 |
This invention relates to vinyl monomer compositions exhibiting accelerated surface cure characteristics. These compositions are prepared from a vinyl monomer or monomer mixtures such as a blend of dicyclopentenyloxyethyl methacrylate and hydroxypropyl methacrylate, a bulk phase polymerization catalyst system, a polyvalent metal oxidative surface phase catalyst, and a diolefin rubber dispersed in the vinyl monomer as a surface cure accelerator. These compositions are useful as binders for polymer concrete and as impregnants for porous surfaces. The accelerated surface cure is particularly advantageous with monomer mixtures containing low volatility vinyl monomers.
