The rigid particles may preferably comprise a polymeric material such as poly allyl diglycol carbonate particles. A method for producing a thermoformed article having a textured surface comprising mixing the syrup as above; swelling the acrylic chips; degassing the syrup; heating the syrup; casting the syrup into a sheet; and thermoforming the cast sheet against a mold.
