ABSTRACT:
A multiribbed plate of an impact-resistant polymethyl methacrylate SP, wherein the impact-resistant polymethyl methacrylate SP is made of:
p1) 4-30 wt % of an elastomer phase E of crosslinked polymer particles VP, made of 60-99.9 parts by weight alkyl acrylate, aryl acrylate or a mixture thereof, 0.1-10 parts by weight of one or more crosslinking agents, and 0-30 parts by weight of one or more monofunctional ethylenically unsaturated comonomers; and
p2) 70-96 wt % of a thermoplastic matrix phase M of polymethyl methacrylate P, containing from 0 to 20 parts by weight, relative to 100 parts by weight P, of units from one or more comonomers,
wherein the elastomer phase E and the matrix phase M have refraction indices which are the same or which deviate from one another by a value n, wherein n.ltoreq.0.02, and the sum of p1) and p2) is 100 wt %, and wherein the multiribbed plate has specific geometric construction requirements providing high impact-resistance and hail resistance.
