An adhesive, which contains olefinic polymers and less than 1% by weight of free monomers, is manufactured via catalytic hydrogenation. It is preferably used in the area of cosmetics, in the foods sector, in medicinal plasters and transdermal systems.

Adhesives with low level of residual monomers and process for

The present invention is directed to methods of preparing hydrophobically-terminated polysaccharide polymers. The methods utilized to prepare the hydrophobically-terminated polysaccharide polymers utilize water as the reaction solvent and do not utilize any cosolvent. The invention is also directed to hydrophobically-terminated polysaccharide polymers which are useful as deflocculants in liquid detergent compositions and to the liquid detergent compositions which contain the hydrophobically-terminated polysaccharide polymers.

Method for preparing hydrophobically-terminated polysaccharide polymers

Polymerizable, saccharide-derived monomers are prepared in processes which utilize water as the reaction solvent and which preferably do not utilize a cosolvent. The saccharide monomers are prepared from a saccharide unit, an amine selected from the group consisting of R.sup.3 NH.sub.2, where R.sup.3 is selected from the group consisting of a C.sub.1 -C.sub.18 alkyl group, H or NH.sub.2, and a single, polymerizable, .alpha.-methyl styryl moiety. The saccharide monomers are useful in preparing polymers for use in freeze-thaw stable aqueous-based compositions which do not require conventional freeze-thaw solvents and colorimetrically detectable polymers which are used in treating aqueous systems.

Polymerizable saccharide monomers which contain a single, polymerizable,
