Plastics are materials which are softened by heat and set into

lasting form when shaped in a mold. Some are natural; some are

semi-synthetic(半合成的) , the result of chemical action on natural

substance; some are synthetic, built up from the constituents of

oil or coal. All are based on the chemistry of carbon, with its

capacity for forming chains. The molecules that compose them

(monomers) link together in the setting or curing(硫化) process

to form chains (polymers) , which give plastics their flexible

strength. Some plastics retain their ability to be softened and

reshaped; like wax, they are thermoplastic. Others set

permanently in the shapes they are given by heat and pressure;

like eggs, they are thermosetting.

From industrial beginnings in the nineteenth century, plastics

have struggled through a hundred and twenty years of glory,

failure, disrepute and suspicion on the slow road to public

acceptance. Now, at last, one can positively say that plastics are

appreciated and enjoyed for what they are; that they make

modern life richer, more comfortable and convenient, and also

more fun. Plastics are warm materials, sympathetic to the human

touch, and their transformation into things that come into

contact with human beings is entirely appropriate.

The fact that there are plastic antiques comes as a shock to

most people. How can a material that seems so essentially

twentieth century, and one that is so much associated with cheap, disposable products, has a history at all? It is a young technology,

and a great part of the fun of collecting plastics is that beautiful

pieces of historical interest can still be found very cheaply.
