lactide

[′lak‚tīd]
(organic chemistry)
A cyclic, intermolecular, double ester formed from α-hydroxy acids; most lactides are relatively low melting solids and are easily hydrolyzed by base to form salts of the parent acid, such as sodium lactate.

Stereocomplexes were successfully formed in poly(lactide)/NR blends (St-PLA/NR) from melt blending.

In the present work, in contrast to the known procedure for preparation of PLA-based block copolymers combining ROP of lactide and controllable radical polymerization, we synthesized PLA-PDMAEMA block copolymers via the aminolysis reaction of PLA chains and RAFT polymerization of DMAEMA for the first time.
First was the evaporation of water and methanol impurities (~347 K) followed by lactic acid (~459 K) and probably lactide (~612 K).
Construction, which is expected to require capital expenditures of approximately 65 million [euro] ($71.5 million) for the PLA plant and 20 million [euro] ($22 million) for the lactide plant, is expected to start later this year with a targeted start-up in the second half of 2018.

Perstorp and Corbion have developed a new lactide caprolactone copolymer that they say delivers "major benefits" in hot melt adhesive applications.
NatureWorks recently introduced a high purity, polymer-grade lactide rich in meso-lactide for the production of amorphous copolymers, adhesives, coatings, emulsions, printing toners, and surfactants.
* A new addition to the Capa portfolio, Perstorp will launch Capa Lactide 8000 series partially renewable polyols for 2 K and 1 K industrial coatings.
For instance, selection of copolymers of various lactide: glycolide with variable molecular weights is an effective way to control polymer degradation rate and drug release.
Corbion Purac's lactide monomers are sourced from GMO-free, renewable feedstocks such as sugarcane, and form the basis for high performance PLA bioplastics.
