1.   Whereas crystallization from dilute solutions may result in the formation of single polymer crystals, this perfection is not achieved when dealing with polymers cooled from the melt.

2.   Plenty of compost helps the sandy soil retain moisture, as do polymer crystals, like Soil Moist.

3.   The special scarf is filled with polymer crystals that absorb water.

4.   These polymer crystals hold water and release it slowly, allowing you to water only every two or three days instead of every day, he says.
