Acrylic compositions for making thermoformable sheets

Disclosed is a process, comprising: (a) mixing polymeric particles dispersed in a carrier with a curable composition; and (b) curing said curable composition, prior to the particles substantially swelling, to form a thermoformable sheet, wherein said carrier is inert relative to said curable composi...

Beschreibung
Zusammenfassung:	Disclosed is a process, comprising: (a) mixing polymeric particles dispersed in a carrier with a curable composition; and (b) curing said curable composition, prior to the particles substantially swelling, to form a thermoformable sheet, wherein said carrier is inert relative to said curable composition and wherein said particles do not swell more than 100% prior to mixing. The disclosure also relates to a thermoformable sheet, for example, an acrylic sheet, comprising particles proximate to the top surface, wherein the textured sheet, when thermoformed, provides a low-gloss, textured surface that is less sensitive to marring, blemishes (including blemishes resulting from the mold), household wear and tear, and visibly reduces the appearance of oil deposits on its surface.
