Abstract
Using optical birefringence, small-angle neutron scattering, and
field-theoretic methods, we study the effects of frustrating quenched
randomness and connectivity on microphase ordering in copolymer melts.
Our results show that randomly grafted copolymers are good model systems
to examine these effects, and we find that these materials exhibit
behavior different from that observed heretofore: for Ether types of
molten polymers. [S0031-9007(94)08822-5].
