FIELD: chemistry.
SUBSTANCE: method of obtaining solid particles involves the following steps: polycondensation of a composition of said polyester in the presence of a catalyst containing at least 5 ppm titanium compounds; adding a catalyst deactivator; curing the composition after achieving characteristic viscosity of 0.69 dl/g until solid particles are obtained, wherein the obtained particles do not contain added aldehyde acceptors; reducing the amount of residual acetaldehyde in the particles to 10 ppm or less without increasing the value of characteristic viscosity by more than 0.03 dl/g. Said catalyst deactivator is added in different conditions which are described in the claim. The method of making articles involves feeding into a processing zone solid particles in a melt and an additional catalyst deactivator containing a phosphorus compound in an amount which satisfies the ratio P:Ti which is less than 2.5:1; melting the particles and making articles.
EFFECT: obtaining solid polyester particles which are used for food containers and beverages without using a solid phase polymerisation technique, and are characterised by low content of acetaldehyde in the absence of organic acetaldehyde acceptors.
