Know-how and expertise

HighperformancePolymers
Researches of high performance polymers, suitable for extreme environmental conditions and exhibiting some specific properties. Development of strategies of macro- molecular chemistry, coupled or not with physical, physi- co-chemical and biological approaches.

Polymersfromagricultural resources
Plastics are part of the every day world and they are used in di erent industrial sectors. The depletion of oil resources worldwide and ecological considerations o er real oppor- tunities for bioplastics. PBS explore new for the synthesis routes for polymers from agricultural resources.

Adaptivepolymers
The adaptive polymers (also named smart polymers) have to possess some properties necessary to the targeted ap- plication, and surface appropriate properties for interaction with the environment they are in. To modulate the cellular proliferation, i.e. inhibit, favor or orientate it, to vector, are important challenges for the pharmaceutical and cosmetic industries, which PBS aims to take up.
