定義
An elastomer used to improve adhesion properties of hot-melt and pressure-sensitive adhesives, as well as for conversion coatings and thermoplastics.
調製方法
Various molecular weights of random ethylene vinyl acetate
copolymers can be obtained by high-pressure radical polymerization,
bulk continuous polymerization, or solution polymerization.
一般的な説明
Poly(ethylene-
co-vinyl acetate) (PEVA) is a flame-retardant material with good mechanical and physical properties. It is majorly used as an insulating material in wire and cable industry.
応用例（製薬）
Ethylene vinyl acetate copolymers are used as membranes and
backings in laminated transdermal drug delivery systems. They can
also be incorporated as components in backings in transdermal
systems. Ethylene vinyl acetate copolymers have been shown to be
an effective matrix and membrane for the controlled delivery of
atenolol triprolidine, and furosemide. The system for the
controlled release of atenolol can be further developed using
ethylene vinyl acetate copolymers and plasticizers.
安全性
Ethylene vinyl acetate is mainly used in topical pharmaceutical
applications as a membrane or film backing. Generally it is regarded
as a relatively nontoxic and nonirritant excipient.
貯蔵
Ethylene vinyl acetate copolymers are stable under normal
conditions and should be stored in a cool, dry place. Films of
ethylene vinyl acetate copolymers should be stored at 0–30°C and
less than 75% relative humidity.
不和合性
Ethylene vinyl acetate is incompatible with strong oxidizing agents
and bases.
規制状況(Regulatory Status)
Included in the FDA Inactive Ingredients Database (intrauterine
suppository; ophthalmic preparations; periodontal film; transdermal
film). Included in nonparenteral medicines licensed in the UK.
