Could a copolymer be formed by both addition polymerisation and condensation polymerisation?

Could a copolymer be formed by both addition polymerisation and condensation polymerisation? If yes, explain with examples and if no, explain with reasons.

Yes, copolymers can be formed both by addidon and condensation polymerisation, e.g. styrene-butadiene rubber, a copolymer, is obtained by addition polymerisation while nylon-6,6 is obtained by condensation polymerisation.
