PROCESS FOR SYNTHESISING ALLYL CARBONATES OF POLYHYDRIC ALCOHOLS AND THEIR DERIVATIVES ABSTRACT OF THE DISCLOSURE: The application relates to a process for synthesising carbonic allyl esters from polyhydric alcohols, which are reacted with diallyl carbonate in the presence of a basic catalyst, which can be chosen from sodium hydroxide, sodium carbonate, sodium alcoholate, organic bases or basic ion exchange resins. The final products obtained differ according to the ratio of the components of the starting mixture. Thus, in the case of diols with a diallyl carbonate/diol ratio great- er than or equal to 10, the resultant product is constituted by the bis allyl carbonate of the diol together with a quantity of less than or equal to 10% of oligomers repre- sented mainly by dimers. If the ratio is less than 10, the percentage of oligomers rises until, in the case of an approximately stoichiometric ratio, it reaches a value close to 70% of the reaction product.
