Disclosed are compositions, systems and methods related to a polypropiolactone composition comprising polypropiolactone polymers. Such polymers include polypropiolactone chains of Formula (I): where n is an integer from 10 to about 1,000 and Y is either —H or a cation.

Systems and processes for polymer production

The present invention provides biodegradable projectiles for toy launchers that contain viable seeds. When lost outdoors the projectiles do not pollute the environment but instead degrade naturally and the seeds grow into plants that enhance the landscape.

Environmentally friendly toy projectiles

In one aspect, the present disclosure encompasses polymerization systems for the copolymerization of COand epoxides comprising 1) a catalyst including a metal coordination compound having a permanent ligand set and at least one ligand that is a polymerization initiator, and 2) a chain transfer agent having two or more sites that can initiate polymerization.
