ABSTRACT:
A monomer-rich acrylic syrup is cast including about 10% to about 20% ground acrylic particles. During curing, the particles absorb over half their weight in monomer, and a cured sheet is formed in which the matrix monomer and uncrosslinked polymer form a phase which extends through the particles, while the particles appear to be fused together. Including a crosslinker in the syrup further insures the interpenetration of the matrix phase into the swollen particles. A textured surface is formed, which is useful as an anti-slip surface in bathtubs and shower stalls, after thermoforming.
