PLCL Morphological Form based on LA:CL ratio

Poly(lactide-co-caprolactone) has a varying degree to glass and melt transitions depending on the LA:CL ratio. In general, the closer the LA:CL ratio is to either end (primarily LA or primarily CL) then crystallinity is enabled for chain-to-chain attraction. When the LA:CL is close to 50:50 mix between the two components then the product has a very low glass transition and melt point with little chain-to-chain interaction. Additionally, the use of more crystalline L-enantiomer lactide improves mechanical durability as well. The morphology (at room temperature) of several of Akina's Products demonstrates this:

Morphology at room temperature (RT):

AP151: PLCL LA:CL 70:30 acid endcap (Mn 75,000-85,000 Da) DL-enantiomer
--> pale straw-colored translucent polymer. Rubbery texture at RT.

AP260: PLLCL LA:CL 90:10 acid endcap (Mn 100,000-200,000 Da) (L-enantiomer)
--> opaque, fluffy, white at RT. Feels dry to the touch.

AP263: PLCL LA:CL 80:20 acid endcap (Mn 75,000-85,000 Da) DL-enantiomer
--> translucent white at room temp. Rubbery texture.
