present and the sequence length is 3 to 50 monomer units” and
“polymerization of [ethylene or] propylene or a 1-olefin of
the formula RCH=CHR’ in which R and R’ are identical or
different and are hydrogen or an alkyl radical having 1 to 14
carbon atoms or R and R’ combine with the carbon atoms joining
them together to form a ring” to produce “syndio-isoblock
polymer[(s)] having molecular chains in which syndiotactic and
isotactic sequences are present and the sequence length is 3
to 50 monomer units” in Dolle’s claims. Randall states
(Randall (EE VI), p. 2083, first sentence of the Synopsis),
“Sequence lengths of stereochemical additions in vinyl
polymers [(including copolymers)] are described in terms of
the number average lengths of like configurational
placements.” Randall’s reference to both polymers and
copolymers is no misnomer. Randall explains (Randall (EE VI),
p. 2083, Introduction, first paragraph, last sentence;
footnotes omitted), “[I]n copolymers, comonomer distributions,
expressed as connecting diads and triads, and number average
sequence lengths can be determined for runs of each monomer
type.”
