Sense: noun/1
'Acrylic' is more specific than 'plastic'. In everyday English, 'plastic' usually means a hard manufactured material for things like bottles, toys, or boxes. 'Acrylic' can be that kind of clear hard material, but it is also a soft synthetic fibre used in sweaters, blankets, and yarn. 'Polyester' and 'nylon' are also man-made materials, but they are narrower in use. Polyester is especially common in easy-care clothing, while nylon is stronger and often used for sportswear, rope, or bags. So if you mean a warm sweater or a clear display case, 'acrylic' may fit. If you mean the broad material category, 'plastic' is safer. Compare: 'an acrylic blanket', 'a plastic bottle', 'a polyester shirt', and 'a nylon backpack'.
Etymology
English took this scientific word in the 1800s from French 'acrylique', a form linked to German 'Acrylsaeure' meaning 'acrylic acid'. The base part 'acryl-' goes back to 'acrolein', the name of a strong-smelling chemical. At first the word was mainly used in chemistry for substances connected with acrylic acid. Later it spread into everyday English for the clear plastic, the artificial fibre, and the paint made from those substances.
