摘要：
1. A CHLOROPRENE ELASTOMER COMPOSITION WHICH COMPRISES A BLEND OF (1) 20-80 PARTS BY WEIGHT OF A GEL POLYMER PREPARED BY POLYMERIZING CHLOROPRENE MONOMER OR A MIXTURE OF CHLOROPRENE MONOMER AND NO MORE THAN 20% OF A COMONOMER IN THE PRESENCE OF 1-10 WT. PERCENT OF A TRIFUNCTIONAL CROSS-LINKING MONOMER BASED ON THE TOTAL MONOMER CONTENT OF SAID GEL POLYMER HAVING THE FORMULA
H2C=C(-R2)-COO-CH2-C(-R1)(-CH2-OOC-C(-R4)=CH2)-CH2-
OOC-C(-R3)=CH2
WHEREIN R1 REPRESENTS A HYDROGEN ATOM, OR A METHYL OR ETHYL GROUP; R2, R3 AND R4 RESPECTIVELY REPRESENT HYDROGEN ATOMS OR METHYL GROUPS, OR IN THE PRESENCE OF 1-10 WT. PRECENT OF A TETRAFUNCTIONAL CROSS-LINKING MONOMER BASED ON THE TOTAL MONOMER CONTENT OF SAID GEL POLYMER HAVING THE FORMULA
H2C=C(-R1)-COO-CH2-C(-CH2-OOC-C(-R2)=CH2)(-CH2-OOC-C(-R4)=
CH2)-CH2-OOC-C(-R3)=CH2
WHEREIN R1, R2, R3 AND R4 REPRESENT HYDROGEN ATOMS OR METHYL GROUPS; AND (2) 80-20 PARTS BY WEIGHT OF A SOL PREPARED BY POLYMERIZING CHLOROPRENE MONOMER OR A MIXTURE OF CHLOROPRENE AND NO MORE THAN 20% OF A COMONOMER.
H2C=C(-R2)-COO-CH2-C(-R1)(-CH2-OOC-C(-R4)=CH2)-CH2-
OOC-C(-R3)=CH2
