Abstract
A biodegradable polymer usable in fishing gear and that biodegrades in aquatic environments. The polymer includes a polymer backbone that has monomeric units that are susceptible to hydrolytic degradation, and a plurality of pH responsive moieties. Each pH responsive moiety is grafted to a respective one of the monomeric units. The pH responsive moieties are relatively hydrophilic when exposed to an aqueous solution of a pro-biodegradation pH range to facilitate hydrolytic degradation of the monomeric units, and are relatively hydrophobic when removed from the aqueous solution of the pro-biodegradation pH range, to protect the monomeric units from hydrolytic degradation.

A biodegradable polymer comprising:
- a polymer backbone comprising monomeric units that are susceptible to hydrolytic degradation;
- and
- a plurality of pH responsive moieties, each pH responsive moiety grafted to a respective one of the monomeric units, wherein the pH responsive moieties are relatively hydrophilic when exposed to an aqueous solution of a pro-biodegradation pH range to facilitate hydrolytic degradation of the monomeric units, and are relatively hydrophobic when removed from the aqueous solution of the pro-biodegradation pH range, to protect the monomeric units from hydrolytic degradation;
- wherein the polymer backbone comprises polybutylene adipate-co-terephthalate and the pH responsive moieties comprise 2-dimethylaminoethyl methacrylate.
A polymer comprising:
- a polymer backbone comprising monomeric units;
- and
- a plurality of pH responsive moieties, each pH responsive moiety grafted to a respective one of the monomeric units, wherein the pH responsive moieties are relatively hydrophilic when exposed to an aqueous solution of a first pH range, and are relatively hydrophobic when removed from the aqueous solution of the first pH range;
- wherein the polymer backbone comprises polybutylene adipate-co-terephthalate and the pH responsive moieties comprise 2-dimethylaminoethyl methacrylate.
