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

## Abstract Head‐to‐head (H–H) poly(allyl alcohol) (PAA) was prepared by the LiAlH~4~ reduction of H–H poly(methyl acrylate) obtained from the methylation of alternating copolymer of ethylene with maleic anhydride. H–H poly(allyl acetate) (PAAc) and H–H poly(allyl benzoate) (PABz) were further deri

## Abstract Head‐to‐head (H–H) and head‐to‐tail (H–T) poly(methyl acrylate)s (PMAs) were hydrolyzed in a mixture of acetone and water (4:1 by volume) at 30°C by using various alkali hydroxides as catalysts. For comparison, the H–T copolymer with 26% H–H units, dimethyl succinate (DMS), dimethyl glu
