The copolymer of chloroprene(CP) and maleic anhydride(MAH) was prepared by radical polymerization. The copolymer was amorphous and had glass transition temperature of about 10℃. The light resistance and the lab shear strength of the copolymer were investigated. The copolymer showed fairly better light resistance under the environmental conditions both exposed to U. V. light and heat. The adhesion strength of the copolymer was determined in terms of lab shear strength as 6.86㎏/㎠ and 4.76㎏/㎠ for the adherend/substrate pairs of steel/steel and copper/copper, respectively.

클로로프렌과 무수말레인산 공중합체를 자유라디칼중합으로 합성하였다. 이 공중합체는 무정형이었고 약 10℃의 유리전이온도를 가졌다. 내광성과 접착강도(lab shear stress)를 조사하였는데 이 공중합체는 폴리클로고프렌에 비해 자외선이나 열에 노출시켰을 때 우수한 내광성을 나타 내었고 철-철 및 구리-구리에 대한 접착강도는 각각 6.86㎏/㎠, 4.76㎏/㎠이었다.
