    Abstract: PROBLEM TO BE SOLVED: To more improve various performance characteristics of a thermoplastic binder, particularly the strength of a molded product produced therefrom as compared with that of the conventional corresponding products thereof. SOLUTION: A method for producing a polymer aqueous dispersion is provided. The polymer aqueous dispersion comprises an emulsion polymer, a polymer composed of at least 5 mass% of an ethylenically unsaturated monocarboxylic acid, dicarboxylic acid or dicarboxylic acid anhydride (abbreviated to an acid polymer SP) and an alkoxysilane represented by the formula SiR R R R [wherein, groups R to R denote each mutually independently an organic group and at least one of the groups denotes an alkoxy group]. The method for production is characterized by producing the emulsion polymer in the presence of at least a small amount of the alkoxysilane by an emulsion polymerization.

    Abstract: The invention relates to the use of formaldehyde-free aqueous binders with broad molecular weight distribution for substrates, comprising (A) 0 to 100 wt. % of an ethylenically-unsaturated acid anhydride, or an ethylenically-unsaturated carboxylic acid the carboxylic acid group of which can form an anhydride or mixtures thereof, (B) 100 to 0 wt. % of an ethylenically-unsaturated compound, (C) at least one polyfunctional curing agent or mixtures thereof and (D) 1 - 80 wt. % of an aqueous polymer dispersion, whereby the polymers from A) and B), obtained by radical polymerisation, on classification in a coordinate system of mean molecular weights Mw and polydispersity values, lie on the surface above a straight line, defined by the linear equation y = 1,25x + 20,000 and displaced in the y-direction by at least + 3,000, whereby the x-axis is the weight average molecular weight and the y axis is the polydispersity value multiplied by 10,000. The invention further relates to the binder itself and the use thereof for example, for moulded bodies, mats or sheets, in particular, for fibrous and particulate substrates such as fibre fleece, glass fibres, rockwool, reprocessed cotton, natural fibres or artificial fibres.

    Abstract: The present invention relates to the use of formaldehyde-free aqueous binders having a broad molecular weight distribution for substrates, said binders comprising (A) from 0 to 100% by weight of an ethylenically unsaturated acid anhydride or ethylenically unsaturated dicarboxylic acid whose carboxylic acid groups can form an anhydride group, or mixtures thereof, (B) from 100 to 0% by weight of an ethylenically unsaturated compound, (C) at least one polyfunctional crosslinker or mixtures thereof, and (D) from 1-80% by weight of an aqueous polymer dispersion, the polymers of A) and B) obtained by free-radical addition polymerization, when classified in a coordinate system by way of their average molecular weight Mw and their polydispersity, being situated in the area above a straight line which is defined by the linear equation y=1.25x+20 000 and has been shifted in y direction parallelwise by at least +3 000, the x axis denoting the weight-average molecular weight and the y axis the polydispersity times 10 000. The invention further relates to the binders themselves and also to their use for, for example, moldings, mats or boards, especially for fibrous and particulate substrates such as fiber webs, glass fibers, rockwool, reclaimed cotton, natural fibers or synthetic fibers.
