Abstract
Biodegradable cross-linked particles, as well as related compositions and methods, are disclosed.
Claims16
A particle, comprising:
- a material comprising a polymer backbone bonded to a chemical species via a 1,2,3-triazole group, wherein the particle has a maximum dimension of at most 5,000 microns and the polymer, backbone comprises polyvinyl alcohol.
A particle, comprising:
- a first polymer backbone;
- a second polymer backbone;
- and
- a 1,2,3-triazole group,
- wherein the 1,2,3-triazole group is covalently bonded to the first and second polymer backbones to cross-link the first and second polymer backbones, and the particle has a maximum dimension of at most 5,000 microns and the first and second polymer backbones comprise polyvinyl alcohol.

A composition, comprising:
- a carrier fluid;
- and
- a plurality of particles in the carrier fluid,
- wherein at least some of the plurality of particles have a maximum dimension of at most 5,000 microns and comprise a material comprising a polymer backbone bonded to a chemical species via a 1,2,3-triazole group and the polymer backbone comprises polyvinyl alcohol.
