摘要：
A method and process for treating leather utilizing selected amphiphilic copolymers is provided. The amphiphilic copolymers are formed from a predominant amount of at least one hydrophobic monomer and a minor amount of at least one copolymerizable hydrophilic monomer. The process is particularly useful as a one step substitute for conventional retanning and fatliquoring treatment steps.
