PURPOSE: To obtain a resin suitable as a material for the production of laminated sheets for electronic devices having excellent low-temperature punchability, by adding a phenol to a low-MW butadiene polymer prepared by a special polymerization method.
CONSTITUTION: A polymer, number-average MW about 200W2,000, is obtained by (co)polymerizing butadiene by using, as an initiator, an alkali metal, e.g., Li, Na or K, or its organometallic compound, e.g., an organosodium of the benzyl (allyl)sodium type and, as a chain transfer agent, an olefin compound of the formula, wherein R
1WR
4 are each H, a C
1W20 alkyl or aralkyl, e.g., ethylene or isobutylene. Next, a phenol, e.g., phenol or resorcinol, is addition-polymerized to said butadiene polymer in the presence of an acid catalyst, e.g., p-toluenesulfonic acid or aluminum chloride.

PURPOSE: To obtain the title resin suitable for use in substrate impregnation varnishes, having improved solubility in organic solvents, at a low cost, by reacting formaldehyde with the addition reaction product between phenol and a liquid polybutadiene.
CONSTITUTION: (B) A phenol is subjected to addition reaction with (A) a liquid polybutadiene having an average molecular weight of 150W5,000 in the presence of an acid catalyst to give a ratio of the number of butadiene monomer units in (A) to that of molecules of (B) of 3W8:1. The reaction product is then reacted with (C) formaldehyde in the presence of a primary amino of the formula R-NH
2 (R is 1W20C alkyl group) solely or in combination with a basic catalyst.
EFFECT: Laminates prepared from the resin have improved mechanical workability, chemical resistance, and curability.
