2)harder
3)more porous
4)less color stable

Question

Quizplus · Accepted Answer

In general,the chemical-cured acrylic resins are more porous and less color stable but weaker and softer than heat-cured acrylic resins.After polymerization,there is more residual monomer in the chemical-cured acrylic,and this initially adversely affects many of the physical properties until the monomer leaches out in minute amounts over several days or weeks.Heat-cured acrylics are harder,stronger,and less porous and have less than 1% residual monomer that leaches out of the surface relatively quickly.
