The present invention provides a resin composition for molding having excellent thermal meltability and capable of providing a molded article that is less likely to crack from a resin weld during use and has excellent surface gloss, and a molded article including the resin composition for molding. Provided is a resin composition for molding, containing: a chlorinated polyvinyl chloride resin; a polyvinyl chloride resin; and a melt additive, the resin composition having an area ratio of a peak B observed in a range of 0.6 to 1.0 ppm to a peak A observed in a range of 9.5 to 10 ppm (Area of peak B/Area of peak A) of 1 to 1,000 when a .sup.1H NMR spectrum is measured by solution NMR.

Described are methods using aromatic vinyl borane monomers for the preparation of highly functionalized copolymers bearing vinyl alcohol, lactone, and ester side chains.

The present invention relates to a method for halogenating an isobutene-isoprene copolymer by using an organic hypochlorite. By using the method of the present invention, a hydrogen halide byproduct may be rapidly recycled into a halogenating agent and reused. As a result, a halogenated isobutene-isoprene copolymer having the high content of secondary allyl halogen functional groups may be prepared by increasing the participation ratio of the halogenating agent in reaction and suppressing the rearrangement of the secondary allyl halogen functional groups. The halogenated isobutene-isoprene copolymer prepared according to the present invention may be effectively used in the crosslinking reaction with other rubber, and is industrially useful.
