V. Bulacovschi et al., SUBSTITUTED OXETANES IN POLYMER SYNTHESIS .2. POLYESTERS BASED ON 3,3-BIS(CHLOROMETHYL) OXACYCLOBUTANE AND POTASSIUM TEREPHTHALATE, Revue Roumaine de Chimie, 40(7-8), 1995, pp. 737-741
The paper investigates the synthesis of polyesters by nucleophilic sub
stitution of chlorine in 3,3-bis(chloromethyl)-oxetane bg potassium te
rephthalate. The obtained products contain the oxetane unit in tile ch
ain anti show anisotropic properties in the molten state.
