    Abstract: A process for the production of a polycarbonate glycol wherein a cyclic carbonate is catalyzed at elevated temperature by a cationic initiator. Compounds of structure (I) ##STR1## where R is alkylene, R' and R" are independently hydrogen, alkyl, alkaryl, aralkyl, or aryl, are heated at an elevated temperature in the presence of cationic initiators such as trimethyl aluminum to form a polymer. Production of a glycol product is assured by subsequent heating at about 200.degree.-220.degree. C. to form a polymer containing carbonate units of ##STR2## and having hydroxy end units bonded to a carbon not part of a carbonate function. The molecular weight of polycarbonate glycol is preferably at least about 1,000. Valuable new prepolymer mixes and polyurethanes may be prepared using the novel polycarbonate glycols of the invention.

    Abstract: Synthesis of methylcyclopentadiene with limited amounts of dimethylcyclopentadiene by-product. Cyclopentadiene monomer is complexed with metallic sodium in diglyme (diethylene glycol dimethylether) and reacted with an alkylating agent such as methyl chloride in the presence of a large stoichiometric excess of cyclopentadiene monomer. A high yield of methylcyclopentadiene is obtained with only a small production of undesirable methylcyclopentadiene. The excess cyclopentadiene is easily recycled in a continuous process.
