in which n is a number from 2 to 10, and
0 to 99% by weight, based on the total weight of cycloolefin
polymer, of one or more acyclic olefins of the formula VIII
in which R9, R10, R11 and R12 are identical or different and are a
hydrogen atom or a C1-C20 hydrocarbon radical; and
said particulate core/shell component consisting essentially
of: one or more rubber phase(s) and one or more hard phase(s),
the hard phase having a glass transition temperature above 50°C
and the rubber phase having a lower glass transition temperature
than said hard phase, said rubber and hard phases consisting
essentiall
y of
polymerize
dunsaturate
dcompounds
having
carbon-
carbon bonds in the polymer backbone.
14. A polymer alloy comprising: (a) a cycloolefin copolymer
component comprising a copolymer of the reactants comprising
norbornene or tetracyclododecene and an acyclic olefin, and
dispersed in said cycloolefin copolymer component, (b) a
particulate core/shell component comprising at least one rubbery
phase having a glass transition temperature below 0°C and a hard
phase having a glass transition temperature above 50°C; the
rubbery phase consisting essentially of, or, if more than one
rubbery phase is present in said alloy, each said rubbery phase
consisting essentially of one or more polymerized unsaturated
