Abstract
PURPOSE: Title composition having improved transparency and mold shrinkage, which is useful as a material for containers, etc., comprising a polymer or copolymer of an aliphatic monoolefin, dibenzylidenesorbitol and tribenzylidenesorbitol.
CONSTITUTION: 1mol of sorbitol and 2mol of benzaldehyde are reacted in the presence of an acid catalyst in two stages. In the first stage, the reaction is carried out at a temperature of 50W70°C, and when the conversion of the sorbitol to dibenzylidenesorbitol becomes 10W40wt%, water and an additional amount of the acid catalyst are added to the reaction mixture. Then, the second reaction in the state of an aqueous suspension is carried out at normal temperature. Thereby, a mixture of dibenzylidenesorbitol and tribenzylidenesorbitol is obtained. Then, the mixture is mixed with at least one polymer or copolymer of an aliphatic monoolefin such as ethylene or propylene to obtain the composition of the purpose.
