Abstract
A prepolymerized resin and a preparation method thereof are provided, the method comprising a step of pre-reacting bis(vinylphenyl)ethane and polybutadiene. Bis(vinylphenyl)ethane may include 1,2-bis(4-vinylphenyl)ethane, 1,2-(3-vinylphenyl-4-vinylphenyl)ethane, 1,2-bis(3-vinylphenyl) ethane or a combination thereof. Polybutadiene has a 1,2-vinyl content of 85% or above and a number average molecular weight of less than 3000. A resin composition comprising the prepolymerized resin and an article made from the resin composition are also provided.
Claims13
A method of preparing a prepolymerized resin, comprising subjecting a composition to a pre-reaction in the presence of a polymerization inhibitor, wherein the composition at least comprises bis(vinylphenyl)ethane and polybutadiene, wherein the polybutadiene has a 1,2-vinyl content of 85% or above and a number average molecular weight of less than 3000, wherein the pre-reaction has a conversion rate of between 30% and 90%, and wherein, during the pre-reaction, components in the composition are partially crosslinked to leave residual vinyl groups.
A resin composition comprising a prepolymerized resin and an additive,
- wherein the prepolymerized resin is prepared by subjecting a composition to a pre-reaction in the presence of a polymerization inhibitor, the composition at least comprising bis(vinylphenyl)ethane and polybutadiene, wherein the polybutadiene has a 1,2-vinyl content of 85% or above and a number average molecular weight of less than 3000, wherein the pre-reaction has a conversion rate of between 30% and 90%, and wherein, during the pre-reaction, components in the composition are partially crosslinked to leave residual vinyl groups;
- and
- wherein the additive comprises polyphenylene ether, cyanate ester, maleimide resin, polyolefin, acrylate, styrene, divinylbenzene, bis(vinylbenzyl)ether, bis(vinylphenyl)ethane, triallyl isocyanurate, triallyl cyanurate, 1,2,4-trivinyl cyclohexane or a combination thereof.
