Block Copolymers

Biodegradable hydrophilic block copolymers. These polymers are block copolymers of hydrophillic, biocompatible poly(ethylene glycol) (PEG), and biodegradable polymers such as poly(lactide-co-glycolide) (PLGA), poly(caprolactone) (PCL), and poly(lactide) (PLA).

Ideal for delivery of poorly soluble drugs such as paclitaxel. PolyVivo polymers can be used for a wide variety of drug delivery platforms, including polymer micelles, thermoreversable hydrogels and other formulations.


Contain reactive or activatable groups for you to customize for your application. Have a specific ligand you want to try out? Have a new targeting strategy? Bring your ideas to the benchtop and animal models quickly by starting with one of Akina's intermediates.

Modified PEGs

Polymers built with polyethylene glycol.


Components used to synthesize a variety of polymers, with no required minimum on the order.


This includes regular PLGA, PLA,bio-inspired and other materials which don't fit into the above categories. Keep in mind on these polymers we don't lock you in to any minumum orders. Purchase as much or as little as you like.

Specialty Polyesters

Biodegradable non-block polymers that can be used for water solubilization or solid phase drug delivery.

Linear Polesters

Biodegradable non-block polymers (Also see: Polyesters arranged by weight, endcap, LG ratios and chirality).

Fluorescent Polymers

"So where did my polymer delivery system go?" is a fairly common question in research. These fluorescent conjugated polymers can be easily seen under most fluorescent microscope systems and other related fluorescent based techniques. Spot and identify your polymers with ease by fluorescence.

Lipid Derivatives

A bio-inspired hydrophobic core combined with a hydrophilic block polymer enables dissolution of poorly soluble drugs while maintaining good micellization and improved circulation.

Polyoxazoline Derivatives

A hydrophilic alternative to PEG, PEOX and derivatives offer for highly functional polymers which can be applied in drug-delivery and medical fields.

The polymers shown are of research grade and are excellent tools for developing drug delivery technology.
