摘要: A chiral (R) stereospecific polyhydroxyalkanoate (PHA) in aqueous latex form having virgin disperse phase particles of very low or undetectable crystallinity is useful in making a water-sensitive structure water-resistant. It may be used as a mixture with a latex of a synthetic polymer. Processes for making the PHA latex are disclosed.
