摘要：
Dry blends (I) for the prodn. of aq. adhesives are claimed, contg. methylcellulose (II), carboxymethyl-starch (III), synthetic resin re-dispersion powder (IV) (opt.) and other additives, etc. (opt.); for easy sepn. of the substrates in the dried blend obtd., the ratio (II):(III) = (3:97)-(30:70). (I) are produced by mixing the dry components or by drum- or spray-drying a slurry thereof. Pref. ratio (II):(III) = (4:96)-(20:80), (5:95)-(10:90); (I) contains up to 40 (10-30) wt% (IV), pref. PVAc; (II) has deg. of methylation = 1.3-2.6, and is pref. ethoxylated and/or propoxylated, pref. with deg. of alkoxylation = 0.05-1.5; (III) has deg. of carboxylmethylation = 0.1-0.7 (DS); other additives are fillers, wetting agents and/or preservatives (below 20 wt% in total).
