专利汇可以提供Stablized polyurethane resin composition专利检索,专利查询,专利分析的服务。并且PURPOSE: To provide a polyurethane resin composition having high heat resistance and good non-extractability, by incorporating, as a stabilizer, a poly (calkylated alkenyl phenol) composed of a specific monomer unit.
CONSTITUTION: The objective composition can be obtained by incorporating polyurethane with, as a stabilizer, preferably 0.003W10 wt% of at least one sort of a poly (alkylated alkenyl phenol) composed virtually of a monomer unit of formula I (R
1 is 1W18C alkyl; R
2 is H or 1W18C alkyl). The stabilizer is a mono-or dialkylated product from the alkenylphenol polymer of formula II; and can be prepared, for example, by alkylation of a polyalkenylphenol with an alkylating agent such as ethylene, propylene, isobutylene, nonene, etc.
EFFECT: The stabilizer has a continued stabilization effect, having good compatibility with polyurethane, along with high migration resistance.
