Abstract

<FORM:0935203/IV(a)/1> <FORM:0935203/IV(a)/2> <FORM:0935203/IV(a)/3> <FORM:0935203/IV(a)/4> <FORM:0935203/IV(a)/5> An edging seal for moulds for polymerization moulding of methylmethacrylate sheets comprises a string of uniform and substantially solid cross-section and consists of 10-80% polyisobutylene and 90-20% polyethylene. The seals may have the cross-sections shown in Figs. 1-5.
