Who invented plastic toys?

During the 65438+60s, due to the shortage of ivory in the United States, there was a lack of raw materials for making billiards. The earliest artificial plastic celluloid was patented in 1869. Although celluloid is the earliest artificial plastic, it is an artificial plastic, not a synthetic plastic. The first synthetic plastic was made of phenolic resin by pressing with a heating mold. It was made by Backlander, an American Belgian chemist of 19 10 in the early 20th century.
