Abstract

A thermoplastic allyloxymethylstyrene-based resin comprising structural units of the following formulas (I) and (II): as repeating units, wherein R represents a hydrogen atom or a hydrocarbon group, and m and n each denote an integer of 0 or 1 or higher, provided that m and n are not 0 at the same time.

Claims (8)

1. A thermoplastic resin comprising structural units of the following formulas (I) and (II):

as repeating units, wherein R represents a hydrogen atom, and m and n each denote an integer of 0 or 1 or higher, provided that m and n are not 0 at the same time, and wherein molecular weight (Mn) of the thermoplastic resin is from 1,500 to 30,000.

2. A thermoplastic resin obtained by polymerizing a monomer having a structure of the following formula (III) by reacting the monomer with a polymerization initiator in a sealed tube at a temperature of 60-140 C.:

wherein R represents a hydrogen atom, and wherein molecular weight (Mn) of the thermoplastic resin is from 1,500 to 30,000.

3. The thermoplastic resin according to claim 2 , which has a degree of cyclization of 80% or higher.

4. The thermoplastic resin according to claim 2 , which has a glass transition temperature (Tg) of 100 C. or higher, but lower than 125 C.

5. The thermoplastic resin according to claim 2 which has a thermal decomposition point of 350° or higher.

6. The thermoplastic resin according to claim 2 which has a moisture content of less than 0.01%.
