    摘要： The invention relates to an agent increasing the rate of hardening of cements, mortars and concretes while maintaining their workability. It also concerns an adjuvant for cements, mortars and concretes, comprising an effective quantity of said agent, and the cements, mortars and concretes comprising an effective quantity of said agent or said adjuvant. This agent corresponds to the formula ##STR1## in which R.sub.1, R.sub.2 and R.sub.3, which may be identical or different, denote the hydrogen atom or an alkyl, substituted alkyl, alkene, aryl or aralkyl group,B denotes a hydrocarbon chain containing at least one --CH.sub.2 -- unit and in which the number of carbons situated in the chain is smaller than or equal to 10,A denotes the groups: ##STR2## in which: X denotes an organic or inorganic anion and in particular a halogenR.sub.5, R.sub.6 and R.sub.7, which may be identical or different, denote alkyl, substituted alkyl, alkene, aryl or aralkyl radicals.

    摘要： A process for improving the mutual compatibility of natural and/or synthetic polymers by the use of cyclodextrin in the polymer mixture, wherein the cyclodextrin represents in particular from about 0.5% to about 20% by weight of the polymer mixture, wherein the polymer mixture includes a starch, in particular a plasticized starch and a synthetic polymer selected in the group consisting of a polyethylene, a polypropylene, a polystyrene, a polyvinyl chloride, a polyvinyl alcohol, and a poly(.epsilon.-caprolactone), wherein the cyclodextrin is provided in the form of a composition containing one of the constituent polymers of the mixture (for example starch), a plasticizer (for example a polyol), a nucleation agent and/or a standard compatibilizing agent.
