Abstract

A process for reclaiming a reinforced acrylic article comprising a GRP layer comprising a glass fiber reinforced material and polyester in which a portion of the acrylic article is subjected to a shear cutting action of such force that the acrylic layer is substantially detached from the GRP layer so as to produce a crude product comprising a mixture of particulate acrylic polymer which is substantially free of GRP, glass fiber which is substantially free of polyester, polyester which is substantially free of glass fiber and residual GRP which is substantially free of acrylic polymer.
