Claims
- 1. Artificial snow in an aggregate form of snow granules which comprises a plurality of nuclei each of which is a super absorbent polymer in granule form and ice layers surrounding said nuclei aggregated by linkage of the adjacent said ice layers or said snow granules.
- 2. Artificial snow in an aggregate form of snow granules according to claim 1 wherein said aggregate constitutes a component of a mixture with a component selected from the group consisting of natural snow, conventional artificial snow and icy snow.
- 3. Artificial snow in an aggregate form of snow granules according to claim 1 wherein said super absorbent polymer retains its original granular form after water absorption without sticking to other granules and has a deionized water absorbability of about 30 to 500 times the weight of the dry polymer and an average particle size of about 20 to 500 .mu.m before water absorption and about 0.05 to 5 mm after water absorption.
- 4. Artificial snow in an aggregate form of snow granules according to claim 1 wherein said super absorbent polymer has an average particle size of about 0.05 to 5 mm after water absorption and a weight ratio of ice to said super absorbent polymer is about 5 to 100.
- 5. Artificial snow in an aggregate form of snow granules according to claim 1 wherein said super absorbent polymer is selected from the group consisting of light degradable polymers and biodegradable polymers.
- 6. Artificial snow in an aggregate form of snow granules according to claim 1 wherein said super absorbent polymer is either odored or colored.
- 7. Artificial snow in an aggregate form of snow granules according to claim 1 wherein said super absorbent polymer is selected from the group consisting of polyacrylic acid salts, vinyl alcohol-acrylic acid salt copolymers and saponified isobutylene-maleic anhydride copolymers.
