Goodfellow PHB Biopolymer (PHB)
Their chemical resistance is somewhat limited as they are attacked by acids and alkalis and dissolve in chlorinated solvents. Rather remarkably, they are optically active polymers with a chiral site in each molecular repeat unit, all of which are in the D- (or R) configuration.
PHB homopolymer is a stiff and rather brittle polymer of high crystallinity, whose mechanical properties are not unlike those of polystyrene, though it is less brittle and more temperature resistant. Hence, copolymers are preferred for general purposes. It is believed that the most likely area for the application of homopolymer is in the medical/biological fields.
Chemical Resistance:
Acids - dilute Fair
Alcohols - Fair
Alkalis - Poor
Greases and Oils - Good
Resistance to Ultra-violet - Fair
