Abstract

A method of manufacturing a thermoplastic resin for a household plumbing equipment includes: reacting an acid component including a terephthalic acid and a glycol component including a trimethylene glycol derived from a plant to form a poly trimethylene terephthalate resin as a condensation polymer of a formed glycol ester; and combining the poly trimethylene terephthalate resin with a polymethyl methacrylate resin in a mass ratio of 90:10-50:50 to form a thermoplastic resin, wherein the thermoplastic resin includes the polymethyl methacrylate resin and the polytrimethylene terephthalate resin in an amount of 80% or more by mass of a total amount of the formed thermoplastic resin.

Claims (8)

1. A method of manufacturing a thermoplastic resin for a household plumbing equipment, comprising:

reacting an acid component including 80% by mol or more of a terephthalic acid or ester-forming derivative thereof and a glycol component including 80% by mol or more of a trimethylene glycol derived from a plant or ester-forming derivative thereof to form a poly trimethylene terephthalate resin as a condensation polymer of a formed glycol ester of the terephthalic acid; and

combining the poly trimethylene terephthalate resin with a polymethyl methacrylate resin in a mass ratio of 90:10-50:50 to form a thermoplastic resin, wherein the thermoplastic resin comprises the polymethyl methacrylate resin and the polytrimethylene terephthalate resin in an amount of 80% or more by mass of a total amount of the formed thermoplastic resin.

2. A method of manufacturing a household plumbing equipment, comprising fabricating the household plumbing equipment from the thermoplastic resin of claim 1 .

3. A method of manufacturing a thermoplastic resin for a household plumbing equipment, comprising:

reacting a terephthalic acid or ester-forming derivative thereof and a trimethylene glycol derived from a plant or ester-forming derivative thereof to form a poly trimethylene terephthalate resin as a condensation polymer of a formed glycol ester of the terephthalic acid; and

combining the poly trimethylene terephthalate resin with a polymethyl methacrylate resin in a mass ratio of 90:10-50:50 to form a thermoplastic resin, wherein the thermoplastic resin comprises the polymethyl methacrylate resin and the polytrimethylene terephthalate resin in an amount of 80% or more by mass of a total amount of the formed thermoplastic resin.

4. A method of manufacturing a household plumbing equipment, comprising fabricating the household plumbing equipment from the thermoplastic resin of claim 3 .
