Novel resin, method for producing the same, novel composition, and cured product obtained by curing the composition

摘要

Disclosed is a resin which is characterized by having a molecular chain wherein a plurality of organic groups represented by the formula (I) below are bound together, and having a weight average molecular weight of 10,000-300,000. (I) (In the formula, C represents a divalent organic group having a divalent hydrocarbon chain with 30-50 carbon atoms; and A represents an amide bond, an ester bond, a urethane bond, a urea bond or a carbonate bond.) This resin is able to exhibit flame retardancy of UL-94 VTM-0 grade without using a halogen-containing flame retardant or a phosphorus flame retardant, and enables to easily obtain a cured product having flame retardancy of UL-94 VTM-0 grade.
