cleaning according to the invention the aqueous suspension of pbbma is applied to the reverse side of the carpets and is polymerized by heating at temperatures above 130 u00b0 c this results in a coating of pbbma polymer which is bound to the carpet in the prior art fire retardants are used in the textile industry however they generally produce light scattering because they are used in powder form according to the invention the aqueous solution of pbbma optionally with complementary components is applied to textile materials and penetrates into the fibers and then polymerization is effected by heating at temperatures above 130 u00b0 c thus polymerizing pbbma and binding the resulting polymers to the fibers addition of free radical initiating catalysts the conventional polymerization catalysts such as organic peroxides e g benzoylperoxide or other free radical producing catalysts e g azobisisobutyronitrile will shorten polymerization time the pbbma suspensions of the invention can be used to copolymerize pbbma with other monomers or grafted to polymers in order to produce adhesives which are also fire retardants or other types of surface modifiers and binding promoters likewise the suspensions of the invention can be used to copolymerize pbbma with other meth acrylate derivatives such as butyl acrylate methyl methacrylate or other monomers to produce transparent plastics of predetermined refraction indices double layered particles can also be produced according.
