Nucleated crystallization of poly(trimethylene-2,5-furandicarboxylate) (PTF) and articles made therefrom
Disclosed herein are compositions and articles made therefrom, the compositions comprising poly(trimethylene-2,5-furandicarboxylate) and one or more of a plasticizer, a neutralized carboxylic acid salt or trisodium phosphate as a nucleating agent, and a copolyester derived from furandicarboxylic acid, 1,3 propanediol and at least one poly(alkylene ether) glycol (PAEG), the copolyester comprising a Furan-PAEG soft segment and a PTF hard segment.
1. A composition comprising:
a) 80-99 wt % of poly(trimethylene-2,5-furandicarboxylate); and
b) 1-20 wt % of a plasticizer of the formula:
A-O—[CHX—(CH 2 ) k —O] j —B,
where
k is an integer from 1 to 3,
j is an integer from 4 to 25,
A and B are each independently selected from an alkyl group, an acyl group, or an aroyl group, each containing 1 to 10 carbon atoms,
X is H, CH 3 or C 2 H 5 ,
wherein the amounts are based on the total weight of the composition.
2. The composition of claim 1 , further comprising 0.1-10 wt % of a neutralized carboxylic acid salt or trisodium phosphate as a nucleating agent, wherein the amounts are based on the total weight of the composition.
3. An article comprising the composition of claim 1 , wherein the article is in the form of a sheet, film, or molded article.
4. The composition of claim 1 , wherein the plasticizer is polyethylene glycol bis(2-ethylhexanoate).
5. The composition of claim 4 , further comprising 0.1-10 wt % of a neutralized carboxylic acid salt or trisodium phosphate as a nucleating agent, wherein the amounts are based on the total weight of the composition.
6. An article comprising the composition of claim 4 , wherein the article is in the form of a sheet, film, or molded article.
7. An article comprising the composition of claim 5 , wherein the article is in the form of a sheet, film, or molded article.
