    Notes: Poly(methyl methacrylate-g-urethane) was prepared by coupling between poly(methyl methacrylate-co-2-hydroxyethyl methacrylate) and polyurethane. The polyurethane was obtained by bulk polycondensation of tolylene diisocyanate and polypropylene glycol. The two polymeric species were synthesized and characterized separately, and the composition of the grafted products varied only by the spacing of the grafted segments. Grafted copolymers with 5, 10, 20, 25, 40, 50, 70, and 90% of incorporated polyurethane have been prepared.

    Poly(methyl methacrylate-g-urethane). II. Thermal and mechanical behavior (1986)

    Notes: The thermal and mechanical behavior of poly(methyl methacrylate-g-urethane) has been investigated. Thermal analysis indicated compatibility between the two polymeric segments up to 15% polyurethane content. Tensile tests revealed progressive change in mechanical properties with composition, and the materials varied from glassy to leathery to rubberlike. Thermal and mechanical results suggested a morphological model where a glassy matrix of poly(methyl methacrylate) mixed with polyurethane is the continuous phase up to 25% polyurethane content, when a phase inversion occurs.
