Product Name

Methoxy poly(ethylene glycol)-b-poly(D,L-lactide)

Structure

Category

Biodegradable Polymers

Synonyms

mPEG-PLA, mPEG-b-PLA

Description

This product is a special polymer prepared by linking methoxy poly(ethylene glycol) and poly(D,L-lactide) segments together.

Molecular Weight

PDLLA average Mn ~5,000
PEG average Mn ~2,000

Molecular Formula

HO[CH(CH3)COO]m[CH2CH2O]nCH3

Application

Biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic poly(D,L-lactide) (PLA) block. These materials have been used in control release and nanoparticle formulation for drug encapsulation and delivery applications. Well-defined materials with varying properties can be prepared by controlling the relative length of each polymer block. Hydroxyl termination allows for facile further chemical modification of these materials.

Features And Benefits

Good biocompatibility;
Properties can be easily modulated by changing the block copolymer segment sizes to suit a particular application.
