IMPREGNATED BODY BASED ON MINERAL FIBRES AND AN ORGANIC BINDER
For moulded bodies, obtainable by impregnation or coating of base mouldings built up mainly from mineral fibres, non-fibrous mineral fillers and starch, with compositions which contain, as binders, copolymers consisting of a) 60 to 95 % by weight of methyl methacrylate (monomer I> b) 5 to 40 % by...

Summary: | For moulded bodies, obtainable by impregnation or coating of base mouldings built up mainly from mineral fibres, non-fibrous mineral fillers and starch, with compositions which contain, as binders, copolymers consisting of
a) 60 to 95 % by weight of methyl methacrylate (monomer I> b) 5 to 40 % by weight of acrylate and/or methacrylic acid (monomers II> c) 0 to 35 % by weight of one or more acrylates of a C1- to C8-alkanol (monomers III> d) 0 to 5 % by weight of copolymerisable, olefinically polyunsaturated monomers (monomers (IV) and
e) 0 to 5 % by weight of other copolymerisable monomers (monomers V) in the polymerised form, the proportions by weight of the monomers I, II, III and V are selected within the indicated limits in such a way that a polymer built up only from these monomers would have a glass temperature of from 60 to 125 DEG C. |
