Abstract

type:Journal Article<br />To achieve the chemical recycling of flame-resisting materials consisting of poly(L-lactic acid) (PLLA), a safer flame-resisting material, PLLA/aluminum hydroxide {Al(OH)3} composite, was investigated the capability of the feedstock recyclability to optically active monomer L,L-lactide. The thermal stabilization of the composite was improved compared to those of as-polymerized PLLA and Al(OH)3 themselves, which makes the melt processing of the composite easier. Nevertheless, at temperatures lower than 300°C the effective depolymerization of PLLA proceeded, without any racemization reaction, to selectively convert into L,L-lactide, with Al(OH)3 acting as a catalyst for the depolymerization. This means that the PLLA/Al(OH)3 composite is capable of reconciling flame resistance with feedstock recycling of PLLA to cyclic monomer.<br />source:http://dx.doi.org/10.1021/ie049208+
