1936 Chem. Abstr. 30 6478/2 Mixts. of polymers or interpolymers of these compds.

1950 Thorpe's Dict. Appl. Chem. (ed. 4) X. 87/2 The product is not a mixture of polymers A-A-A-A-A-A-...with B-B-B-B-B-B-..., but an interpolymer, e.g. A-B-A-A-A-B-A-A-..., the order in which the units are arranged not being readily determinable.

1955 Jrnl. Polymer Sci. 18 129 A general method of producing graft and block interpolymers between elastomers is therefore indicated.

1966 M. L. Miller Struct. Polymers ix. 426 Polymers made up of molecules containing two or more types of monomer units are called copolymers or interpolymers... The terms ‘copolymer’ and ‘interpolymer’ are essentially equivalent but the term ‘interpolymer’ is more restrictive because it implies an intimate distribution of monomer units in the molecule while the term ‘copolymer’ has no such implication.

1950 Thorpe's Dict. Appl. Chem. (ed. 4) X. 87/2 Vinyl acetate is interpolymerised with vinyl chloride to give plastics which are lower softening and more soluble than polyvinyl chloride.

1950 Thorpe's Dict. Appl. Chem. (ed. 4) X. 88/1 There are monomers..which do not give high molecular-weight polymers by themselves but may readily interpolymerise with a second component... Interpolymerisation may even be effected in cases where neither component is separately polymerisable.
