## Abstract Head‐to‐head polyisobutylene degrades at a maximum rate at 320°C, a temperature about 65°C lower than head‐to‐tail polyisobutylene. Under our conditions, head‐to‐tail (the regular polyisobutylene) degrades (as do many other disubstituted vinyl monomers) to a high yield of the monomer is

The behaviour in dilute solution of head-to-head (H-HI polypropylenes, covering the range M,, = 0.22 to 4.19 × 104, has been studied in cyclohexane as solvent at 303 K. The data could be represented by two distinct Mark-Houwink equations describing the low and the high molecular weight regions. The

A greatly improved and very reliable synthesis of head to head polystyrene (HHPS) was worked out. HHPS was prepared in a sequence of four steps starting with a reductive photodimerization of acetophenone. The resultant 2,3-diphenyl-2,3-butanediol was dehydrated in vacuum to 2,3-diphenyl-1,3butadiene
