초록

In order to impart new functions to poly(trimethylene terephthalate) (PTT) and to remove several well-known disadvantages of PTT such as changes in physical properties with ageing especially for undrawn and/or partially drawn PTT yarn a new type of polyesteramide based on PTT, poly(trimethylene terephthalate-co-trimethylene terephthalamide) [P(TT/TA)], has been synthesized using dimethyl terepthalate (DMT), T3T-dimethyl ((benzoic acid, 4-4'-[1-2-propanediylbis (iminocarbonyl)]bis-dimethyl ester) and 1,3-propanediol as monomers and tetraisopropyl titanate as a catalyst through a DMT process. The feed ratio of T3T-dimethyl was varied from $5-15mol\%$. The content of TA unit in P(TT/TA) was lower than the feed ratio of T3T-dimethyl. Intrinsic viscosity and melt viscosity of P(TT/TA) increased with increasing content of TA unit. Thermal properties of P(TT/TA) were also measured as a function of TA content using DSC and TGA.
