noun
a polymer consisting of a chain of identical molecules
homopolymer in American English
(ˌhouməˈpɑləmər, ˌhɑmə-)
noun
Chemistry
a polymer consisting of a single species of monomer, as polyadenylic acid or polyglutamicacid
Word origin
[1945–50; homo- + polymer]This word is first recorded in the period 1945–50. Other words that entered Englishat around the same time include: beeper, fail-safe, regression analysis, synchronized swimming, taxi squadhomo- is a combining form appearing in loanwords from Greek, where it meant “same” (homology). On this model, homo- is used in the formation of compound words (homomorphic). Other words that use the affix homo- include: homodyne, homogamous, homogentisic acid, homograph, homologous
