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 greater 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 represented mainly by dimers. If the ratio is less than 10 …
